Best Sharpeners for Gardening & Landscape Tools: Guide, Reviews & Recommendations

We independently evaluate all recommended products and services. If you click on links we provide, we may receive compensation.

Does it really make sense to buy a new pruner, lopper, lawnmower blade, machete, hatchet, axe, shovel, hoe, hedge shear, or knife just because the one you have is dull? Does it make sense to take time out of your busy day or precious weekend to drive to a tool sharpening place that may or may not have same day service?

We think there’s a better way. All it requires is a little education and the purchase of some affordable sharpening tools.

But with so many options for sharpening your gardening and landscape tools, where do you turn? There are clearly a lot of choices, so we’ve taken the guesswork out by reviewing a wide variety of tool sharpeners so we can recommend the best options for your sharpening needs.

TYPES OF SHARPENERS

We did not cover every conceivable sharpener currently on the market as we’d never get this review written. But what we did do is pick some well-known manufacturers with a history of providing good to excellent quality gear that will get the job done.

We focused our attention on the following types of tool sharpeners:

Metal files
Bonded abrasive whetstones (man-made, rather than those cut from the earth)
Carbide sharpeners (“V” shaped, chisel-shaped, and flat shaped)
Diamond impregnated tapered rods
Diamond impregnated double-sided sharpeners (sometimes called “paddle” sharpeners)
Ceramic stones and diamond impregnated triangular stones
Electric motor, belt-driven sharpeners and grinders

Questions to Consider When Choosing a Sharpening Tool

Choosing the right sharpener for the job is both subjective and objective. It’s also a function of what tools you own.

Here are some questions to help you figure out what you need.

What’s my budget?
What sharpening tools do I already have?
What gardening and/or landscaping tools do I own?
Can I get by with just one sharpener for the tools I own, or does it require multiple types of sharpeners?
Do I want to deburr the edges of my tools to make them very sharp?
Do I care if the sharpened edge is a little ragged or do I prefer a finely polished surface?
Is MY take-away “It’s good enough” or “I’m a perfectionist”?
Am I a tool junkie or a minimalist?
Am I planning on sharpening friends’ and family tools? If so, what kind of tools do they have?
Do my tools have straight, curved, or serrated edges, or all three?
Do my tools have serrated edges, how close together are the serrations?
Am I a “tool for life” person or would I rather just rather buy a new one when needed?
Should my sharpener be multi-function (with the ability to sharpen many different types of tools)?
Is size/transportability important?
Are corded and/or cordless sharpeners a consideration?
How hard is the metal I’m sharpening?
How quickly do I want to get the job done?

With those questions in mind, take a look through the following sharpening tool descriptions to see which will be the best option(s) for you.

the different types of sharpening tools

Click on each sharpener type below to view the details.

Metal Files

These are the kind of metal files that come either individually or as a set. They’re often referred to as a mill Bastard file and are typically available online or at a hardware or big box store.

Metal files are not only useful for sharpening gardening and landscape tools, but have other filing uses as well (for example, squaring off a PVC pipe that has a been cleaved with a rough cut, removing the end of a bolt down to the nut).

Uses

Quickly removing a lot of material from a gardening or landscaping tool’s edge

Pros

Low price
Takes off a lot of metal relatively quickly (depending on how sharp the file is)
Comes in different shapes (flat, round, half found, triangular, etc.)
Comes in different lengths for easy storage or for longer filing strokes
Lasts a long time (if properly cared for)

Cons

Uncomfortable to hold the “tang” unless purchased with a handle (the handle is often sold separately and can be used on multiple files)
The file’s metal cutting ridges tend to collect filings and debris and have to be cleaned often. A “file card” brush is used to clean the cutting grooves but must be purchased separately.
Tends to rust easily (if not oiled or protected from the elements)
Tends to leave a rougher cutting edge. Don’t use a metal file on fine knives, scissors or anything requiring a very clean/fine edge.
Can leave groove(s) in the material if you’re not careful to keep the file moving in a sweeping motion (not just back and forth in one area).

metal files for sharpening gardening tools

Metal files come in a variety of shapes. Buy a handle and “file card” when you purchase one.

Recommendations

You can’t go wrong with owning at least one metal file. Just make sure you purchase a “file card” (to remove excess filings and debris from the grooves of the file) and a handle. Your file and palm will thank you for both. These two items shouldn’t set you back more than $15.00, perhaps a little more if you want to purchase multiple file handles.

There are many manufacturers of metal files. We reviewed a set of metal files by Corona and can highly recommend their brand. Corona also sells file “kits” that have multiple shaped files and include a handle.

No products found.

Nicholson 10" File Card and Brush - 21467

If you don't own a file card, it's best to buy one when you purchase your metal file. The file won't work for long without the file card.

Whetstones

Manmade sharpening stones typically remove a lot of metal and may be substituted for a metal file

These types of whetstones are man-made (with a bonded grit surface), rather than natural whetstones which are made from a slab of specialty stone.

Uses

Removing a moderate to large amount of metal in a short period of time

Pros

Low price
Takes off a moderate to large amount of metal on each stroke, depending on the coarseness of the grit
Can last a long time (if properly manufactured and cared for)
Is a good alternative or supplement to a metal file
Does not require oil or water to lubricate the surface while in use (some of the natural stones may require lubricant)
Makes a good deburring tool

Cons

Can easily chip or break if dropped
If the grit is not bonded tight enough in the manufacturing process, a lot of excess grit will wear off the stone and fall to the floor, making for an after-sharpening cleanup chore.
Tends to develop concave or convex wear patterns on the stone’s surface if used repeatedly in one area.

Man-Made Bonded Whetstones We Reviewed

Recommendations

I preferred the round cap of the Smith’s® sharpener (used to hold onto the sharpener) over just a straight stone like the one from Lansky®. But in terms of overall performance, I recommend the Lansky® Lawn & Garden Tool Sharpener. It held up better to the rigors of sharpening heavier, blunter tool edges, like shovels, hoes, and lawnmower blades.

The real deciding factor was that the Smith’s® stone was much softer and a lot of grit scraped off the stone and ended up on the floor. Also, because the stone was not as hard as the Lansky® sharpener, the Smith’s® whetstone developed grooves in the stone very early into the sharpening test.

Price Reduction

Lansky Lawn and Garden Sharpener: Multi-Purpose Sharpening Stone - LGRDN

An excellent choice for sharpening heavier, blunter tool edges, such as shovels, hoes, and lawnmower blades.

Carbide Sharpeners

AccuSharp carbide sharpeners

Carbide sharpeners are made with either a single or double set of tungsten carbide inserts (they're incredibly hard) that are dragged over the edge of the implement being sharpened.

Uses

For quick touch-ups or aggressive metal removal

Pros

Low price
One of the easiest and quickest ways to put an edge on a tool (as long as the width of the edge will accommodate the carbide spacing)
Reversible carbides (except the Corona AC 8300) for longer tool life
Replaceable carbides can be purchased for the existing tool without having to buy a brand new tool (except the Corona AC 8300).
Lightweight
The tungsten carbide inserts (the sharpeners) will not rust
Certain models will sharpen scissors, others will put a knife edge on axes, machetes, hatchets, knives and more. And still other designs will put a chisel edge on lawnmower blades, loppers, pruners, hoes, shovels and virtually any chisel ground edged piece of gear.

All three manufacturers of the carbide sharpeners we reviewed had a clear winner, depending on the use

Cons

The sharpened edge is more ragged (and can leave burrs) than when sharpened with diamond impregnated tapered rods/triangular stones, paddle files or ceramics.
A lot of material can be taken off quickly from precision cutting blades if too much pressure is applied, leaving an uneven cutting surface.
Based on the design of some of the carbide sharpeners, they will not fit in tight places to fully sharpen a blade.

Overall Impressions

If you’re primarily interested in an inexpensive tool that does a good job at putting a pretty good (but not the best) edge on a variety of tools, a carbide sharpener is definitely something to consider.

I’ve had a lot of experience with these sharpeners. I owned a tree care company for many years and used one of the AccuSharp sharpeners to put a chisel grind edge on my chipper blades. Although the blades were sharp and did their job, I found that the aggressive carbide put slight ridges in the blades. These ridges were exacerbated the more I used the sharpener. Eventually, I had to send the blades out to be machine ground to remove the ridges.

I also found the same to be true for fine cutlery. The factory edge was replaced with one that was sharp but not as sharp as one honed by diamond impregnated tools or ceramic sharpening technologies.

In my recent testing, I found the carbides very aggressive. If you’re not careful, they can take off more than you intended. I’ve also found that when the carbide inserts get dull, they take off inconsistent amounts of material or virtually none at all.

BUT, with all that said, carbide sharpeners are a great bang for the buck. If you want a quick edge and you’re not a perfectionist, you definitely can’t go wrong with a carbide sharpener.

Recommendations

Depending on the task, I had favorites from each manufacturer.

For sharpening the chisel grind edges of bypass pruners, loppers, stick pruners and hedge shears, and the cutting blades on anvil loppers, I preferred the Corona AC 8300 SolidCARBIDE.

Corona AC 8300 SolidCARBIDE

For knives, axes, and similar tools, I preferred the AccuSharp Knife and Tool Sharpener and the AccuSharp Sharpener for Axes/Machetes/Knives (non-serrated)/Hatchets & More.

AccuSharp Tool Sharpener

Perfect for a range of sharp-edged tools, such as axes, machetes, large non-serrated knives, and hatchets.

For lawnmower blades, shovels, hoes, and hori horis/digging knives, I thought the Smith’s Mower Blade Sharpener was the clear winner.

My recommendation for lawnmower blades, shovels, hoes, and hori horis or digging knives

I experimented with the AccuSharp ShearSharp on a pair of kitchen scissors and found that it did the job but left significant burrs, which I had to remove with a ceramic stone. A great concept, but something I would leave for other sharpeners (like the Spyderco Tri-Angle Sharpmaker).

Diamond Impregnated Tapered Rods

diamond impregnated tapered sharpening rods

In their closed position these types of sharpeners are an easy carry in your pocket

These steel rods have small diamond particles bonded to the surface. When moved across the surface of a softer material (such as the steel used in garden and landscape tools), the diamond particles wear down/off the softer steel.

Uses

For precision sharpening a variety of edged tools

Pros

Diamonds are really hard and when properly applied to a steel rod, they last a long time.
Great for getting into circular pockets of tools like hori horis, the Lesche Digging Tool, the wire cutting notch of a bypass pruner, and scalloped pockets of hedge shears.
Excels in sharpening knives, chisel ground edges and serrated blades
Leaves a smooth cutting edge
Fits into tight places where other sharpeners fail
Nice deburring tool
Collapsible handles or storage tube minimizes carry size

Cons

Not recommend for taking off large amounts of metal
Takes some practice to get a factory knife-edge angle (without over or under doing it)

Diamond Impregnated Tapered Rods We Reviewed

Recommendations

Right out of the gate, I’ll tell you I’m a “tool for life” guy. I believe in spending the extra money on quality as I want it to last for a LONG time. Other might disagree.

For me, the clear winner in this category is the DMT DiaFold® Serrated Sharpeners. They offer three different grits (coarse, fine, and extra fine). If you want a highly polished, frighteningly sharp edge, then the three-rod package is for you. It will set you back though. Each grit size is in the $25 - $30 range. Part of the cost comes from the quality of the diamonds and substrate steel, and the other is that they are made in USA (which tends to be more expensive than overseas production).

I can attest to the longevity of the DMT sharpeners. I’ve had a set of DMT Dia-Sharp® Bench Stones, have used them regularly for 25 years, and they are still going strong.

And as a final note, they have the smallest tip diameter (for getting into those really small serration pockets) of any of the rod sharpeners I tested (except the Smith’s PP1 –Tactical, which I’ll address below).

Price Reduction

DMT DiaFold® Serrated Sharpeners

Available in a variety of grits, these are the best diamond impregnated tapered rods I've used to date.

Next comes the rods from AccuSharp and Smith’s. At a first glance, they look identical except for the color of the tubular housing (Smith’s is a yellowish/orange and AccuSharp is black). With the diamond tapered rods extended to their proper length, the AccuSharp is just a hair longer. The tip diameter is the same for both, and both are made in China. To the touch, the diamond grit appears to be the same (coarse). Based on Amazon pricing, the Smith’s would be about two dollars less expensive. They both had the same performance. I’d go for the Smith’s.

Smith's DRET Diamond Retractable Sharpener

Smith’s PP1-Tactical Sharpener

Here was the wildcard of the bunch. Not only does it have a tapered diamond rod, but also has a carbide (coarse grit) sharpener and a ceramic (fine hone) knife sharpener, plus an emergency glass breaker. This is a 4-in-1 tool. It also has a handy pocket clip and a lanyard slot.

But let’s talk about the diamond rod. Of those tested, it had the smallest diameter tip by 0.01”. But in practical terms, this is not a replacement for the above rods. The above (DMT, Smith’s, AccuSharp) tool tips will fit most serrations AND they have an upper limit rod diameter that will sharpen the larger serration pockets of most knives on the market. I found in my tests that the PP1’s largest rod diameter would not properly sharpen standard sized serrations.

However, used as an edge-sharpening rod, it worked great. The grit felt coarse, just like the coarse grits of the other tapered rod sharpeners.

I did try the carbide and ceramic sharpeners on anvil pruners (they have a knife edge) and it worked. But it doesn’t have the proper guards for this application. I slipped and got a little nick on my finger (nothing to write home about).

This is definitely a knife sharpener, with the tapered rod used mostly for sharpening knives and less for sharpening serration pockets. It’s a handy tool for the right application.

If you’re a landscaper or gardener who carries a straight bladed knife on you as part of your kit, then I would definitely consider this all-in-one sharpener. Cutting string, rope, burlap, landscaping fabric, roots, soil, etc. can mean you’ll need to sharpen a knife daily (or many times per day). This well-designed tool would be perfect for these applications. And at about $19.00, I think it’s a bargain.

Diamond Impregnated Double-Sided Sharpeners (Paddle Files)

With handles folded or the sharpener inserted into the handle (Smith’s), these types of sharpeners are easy tp transport

These flat sharpeners, sometimes called “paddle sharpeners” or "paddle files", have two usable sides. Depending on your preference, these can have extra fine, fine, medium or coarse grit (diamond particles bonded to the metal substrate). In this review, we looked at paddle sharpeners with a fine and a coarse grit side.

Uses

To sharpen a variety of garden, lawn and landscape tools

Diamond Double Sided Sharpeners have both a coarse and fine side making them useful in material removal and honing

Pros

Has two different grits, one on each side (we looked at fine/coarse grit paddles), making it a multi-use tool
Long-lasting diamond impregnated surfaces
Best used for medium metal removal and edge touch-ups and deburring
Compact when files are folded or inserted into the handle
Leaves a nice clean, sharp edge (when using the fine grit)

Cons

Difficult to use on tight concave surfaces
Not an aggressive metal removal tool (in comparison to a whetstone, metal file or carbide)
Won’t fit in a lot of places that a diamond tapered rod will

DMT Diafold Double-Sided Sharpener

I know you probably think I’m biased by saying that the DMT DiaFold Double-Sided Sharpener is my favorite in this class of sharpening tools. Quite simply, it’s an excellent sharpener (for the same reasons as described above for their tapered rod). But it’s expensive. Enough said.

Smith’s Diamond Combination Sharpener

Of the other three, I’d have to go with the Smith’s Diamond Combination Sharpener. I like its handle design. Instead of having two handles that fold around the stones (also the reason that this class of sharpener is called a “paddle sharpener”), there’s a single handle into which the double-sided sharpener is inserted. At first I thought this would make for a wobbly product, but after use it was rock solid.

I also like that the Smith’s has an oval polka dotted surface (similar to DMT’s), to catch the metal filings (called swarf). This makes the file more efficient and less likely to clog up. It also has a Micro-Tool Sharpening Pad^TM giving it the ability to file small tools (such as points on a metal gardening stake) “that require an uninterrupted sharpening surface”.

Finally, of all the diamond double-sided sharpeners, Smith’s Diamond Combination Sharpener has the finest grit on the fine side of the sharpener, making it that much easier to obtain a super sharp edge. I found it especially great for sharpening hedge shears and deburring a nice smooth edge on a tool that had been sharpened with a more aggressive tool, such as a carbide, metal file or whetstone.

Ceramic Stones & Diamond Impregnated Triangular Rods

The Spyderco Tri-Angle Sharpmaker sharpens so many tools and them some

Ceramic stones are made from synthetic sapphire, making them very hard and an excellent tool for sharpening metal implements. Diamond impregnated triangular rods have small diamond particles bonded to a metal surface.

Uses

Multiple sharpening applications

Pros

Fits into very small serrated pockets (not reachable with a tapered diamond rod).
Extremely long life (equal to if not longer than diamond impregnated sharpeners and certainly longer than a metal file).
Great for keeping what is already sharp - extremely sharp vs. heavy duty material removal.
Easy to use.
Can sharpen a variety of knife edges or chisel ground tools including scissors and chisels (for tree root pruning).

Cons

Ceramic sharpeners if dropped can chip or break.
Remove the least amount of material of all the sharpeners (except the diamond impregnated triangle rods).

Recommendations

Spyderco 400F

This tool was initially designed “for sharpening detailed tools like woodcarving tools, gouges, and dental devices”. I specifically requested this set to file some super small serrations in the Fiskars Billhook. The triangular and teardrop files were absolutely perfect, reaching all the nooks and crannies in the blade and making the Billhook extremely sharp. In contrast, even the smallest diameter diamond tapered rod ground the tops off these serrations, making them useless. (As you’ve probably gathered by now, I’m a perfectionist and needed the right tool for the right job.)

The Spyderco 400F set also includes a square and round file. These are nice to hone the edges of pruners, loppers, hedge shears, stick pruners and the like. Their small size (5” long) makes them ideal for intricate work and easy to carry into the field. They come in a nice leather pouch.

For intricate filing of extremely small, serrated edges and honing other precision tools, the 400F by Spyderco is absolutely terrific

Spyderco Tri-Angle “Sharpmaker”

The utility of this sharpening tool is almost endless; it will sharpen just about anything that is already semi-sharp. The sharpener comes in a case that holds four rectangular stones (two coarse grit and two fine grit). Both sets of stones are made from synthetic sapphire and are extremely hard. They’re so hard, you can even use them to remove metal from the edge of a hardened metal file.

In addition to conventional stones for the Sharpmaker, you can also purchase diamond-impregnated (hardest) and cubic boron nitride (second hardest to the diamond) ones. I found the diamond-impregnated stones to be indispensable in removing a little more material faster than just the ceramic stones. They were also great for sharpening a hatchet.

The system is made for sharpening all kinds of tools, but for the gardener and landscaper, it excels at knives (both straight edged and serrated), hatchets, pruners, loppers (both anvil and bypass), machetes, box cutters, diagonal cutters, scissors, and more.

The stones are tough but are not designed to remove large amounts of metal (like a metal file or manmade grit stone). The Sharpmaker ceramic stones are ideally suited for keeping what’s modestly sharp, razor sharp.

The sharpener has a base plate for inserting the stones at either 30⁰ or 40⁰angles, a set of brass rods as a safety system to; protect from accidentally cutting yourself; or tilting up unit for other sharpening tasks. A slot positioned at the end of the base plate is for sharpening scissors, etc. There are also stone holders on both the top and bottom of the base plate that hold the stones flat for sharpening things like chisels (for tree root pruning), etc.. And finally, another important feature of this sharpener is that the triangular stones can be used on their own (not installed in the base plate) for sharpening pruners, loppers, hedge shears, or any type of gardening tool that has a knife or chisel grind edge. And as a side note, it works like a charm for kitchen knives as well.

For someone who wants a keep sharp and deburr a variety of gardening and landscape tool, you can’t go wrong with a Spyderco Tri-Angle Sharpmaker. I’ve had one for over 15 years (with the original stones) and it is still going strong.

This combination belt-drive grinder and sharpener isn’t your typical hand-held tool like the other sharpeners in this review, but if you have space for an electric sharpener, these types of tools can be invaluable.

Uses

Sharpens knives (straight blade and serrated), scissors, garden, and landscape tools

Pros

Powerful electric motor for grinding applications
Various grit belts from grinding to honing
Pivoting head for easy conversion from sharpening to grinding
Two different guides (for sharpening specific tools at specific angles)
Three position switch (Off, Grinding – ON, momentary sharpening)
Belt tracking adjustment knob
Quick-lock tensioner for belts
Belts are easy to change
Great for sharpening gardening and landscaping tools where a lot of material needs to be taken off

Cons

Won’t set a factory ground chisel angle on bypass pruner and lopper blades, or on anvil lopper blades
Has an electric motor so can’t be used to sharpen tools in the field (unless you’re near an electrical outlet and have an extension cord)
Too aggressive on fine cutting tool blades (such as pruners and loppers), based on the recommended grit for performing these operations

The Work Sharp package comes complete with sharpener/grinder, guides and various grit belts

Recommendation

This is a really awesome tool. The design was well thought out and it is easy to use. If you want to remove some serious material from a gardening or landscape tool (such as a shovel, hoe, hatchet, tines, axe, lawnmower blade, or landscape bar) then this is the tool for you. It converts into a grinder and makes quick work of a variety of tools.

The unit comes with several grinding/sharpening/honing belts (two 80 grit, two 220 grit, and two 6000 grit), a 25⁰ Outdoor Guide (for sharpening serrated edges, hunting knives, pocket knives and scissors), and a 20⁰ Kitchen Guide (for sharpening kitchen knives and filet knives). After a Guide is removed, the head of the unit can be rotated forward to turn it into a belt grinder.

Also included is a well-written instruction manual. Plus, Work Sharp has an excellent website tutorial to get you up and running.

This is a real winner in my book and a must have for the serious gardener and/or landscaper. It won’t accommodate all of your sharpening needs but it comes pretty darn close.

Comes with easily-replaceable abrasive grit belts (coarse P80, medium P220, and fine 6000) and precision sharpening guides. 1-year warranty.

Summary

Hopefully, we’ve shed some light on some of the sharpening tools that are readily available for the gardening and DIY landscape enthusiast. Clearly, there are a lot of choices.

In my opinion, you’ll need more than one tool to get the job done right, particularly if you own different types of gardening tools.

The best sharpening tool for your needs will vary based on which tools you'll be sharpening, whether you prefer electric or "person-powered" sharpeners, how quickly you want to get the job done, and more.

For perfectionists like me who want only the best quality (even if it's at a higher cost) because they want it to last a lifetime, there are some brands that consistently put out excellent sharpening tools (DMT and Spyderco come to mind). But there are plenty of more moderately-priced options that will also do a very good job.

Basically, there's something for everyone in the list of recommended sharpeners below!

OVERALL RECOMMENDATIONS

Metal Files

You can’t go wrong with a set of good quality metal files. Corona sells sets of them and you can also buy handles for them (get the handles, you’ll thank me for it). You can bull your way through about any metal and a variety of angles (even concave if you get a round file). My pick is Corona.

No products found.

Whetstones (man-made)

I’d go for the Lansky whetstone. Although the Smith’s whetstone sharpener did its job, it left a fair amount of the stone’s abrasive on the floor and tended to develop grooves in the stone more quickly than the Lansky.

Lansky Lawn & Garden Tool Sharpener

An excellent man-made whetstone that gets the job done without leaving a mess behind

Carbide Sharpeners

I tested three different manufacturers of Carbide sharpeners: AccuSharp, Smith’s, and Corona. Each company manufactured a winner in my mind – any would be a good choice (more above).

Diamond-Impregnated Tapered Rods

When it comes to diamond tapered rods, I’d go for the DMT sharpeners due to the quality and the precision that comes from having three different grit sizes to choose from. They are also made in USA – I like purchasing in-country when I have the opportunity. Otherwise, one by AccuSharp or Smith’s will do the trick. They are virtually the same.

Price Reduction

DMT DiaFold® Serrated Sharpeners

Available in a variety of grits, these are the best diamond impregnated tapered rods I've used to date.

Multi-Tool Sharpeners

The PP1 Tactical from Smith’s is a great multi-tool and is definitely handy for sharpening knives and smaller serrations. I see it more for the DIY landscaper who needs to constantly sharpen a knife for the work they do. And who wouldn’t want an emergency glass breaker – just in case. As a gardening tool probably not, but then again plenty of gardeners carry a multi-tool into the garden and use it frequently.

Double-Sided Diamond-Impregnated Sharpeners / Paddle Files

Outside my go-to preference for DMT, I’d recommend the Smith’s Diamond Combination Sharpener. Its plastic polka dots to accept the swarf, combined with pretty standard coarse and fine grits, make it a great choice. The handle is beefy, rigid and strong and I like the way the file stores inside the single-piece plastic handle. It also cut into the metal more smoothly than the others (except DMT).

If you’re after fast metal removal then the Lansky Sharpening Paddle is for you. Of the above tools I tested, most have a coarse grit in the 320 range and a fine grit in the 600 – 750 range (the smaller the number the coarser the grit). Lansky’s coarse grit came in at 120. This is by far the most aggressive coarse file I tested. If you had to choose between a man-made whetstone versus the Lansky Diamond Sharpening Paddle, I’d go for the paddle. I wasn’t a real fan of the handle design - the handles flopped around when not in the “in-use” position, but they did stiffen up when brought together to do the work. This is an example of where one tool could substitute for another.

Ceramic Sharpeners

We only had one contender in the Ceramic Sharpeners category (diamond rods included) and that was Spyderco. I’ve owned one of their Tri-Angle Sharpmakers for many, many years. It has been my go-to for knives, scissors and many other cutting tools. But its sharpening abilities don’t stop there. The ceramic sharpening stones can be used on their own to sharpen and deburr a variety of gardening and landscape tools, as well as to put both chisel and knife edges on pruners, loppers, shears and the like. This is not a heavy duty metal removal kit but, rather, a “keep it sharp” tool for use when an edge becomes dull.

And let's not forget the 400F ceramic rod sharpening kit. Some may see this as an extravagance but it sure did the trick when honing those hard to get serrations or putting a mirror-like finish on a set of pruners. Is it a must? Not for most. But for me, the owner of a Fiskars Billhook, it’s indispensable.

And as an upgrade to the Tri-Angle Sharpmaker, Spyderco offers a set of diamond impregnated sharpening rods. These were a nice addition when I wanted to sharpen a hatchet while using the Sharpmaker base, or when used as a single rod to touch up a machete, wire cutters or hori hori.

Electric Tool Sharpeners

The Work Sharp is an impressive multi-tool. Part sharpener, part grinder, it sharpened/honed a lot of tools.

I used it to put a new tip on a broken knife and it performed beautifully. Not only did it remove considerable material (to put a point back on the blade), it honed it to a gleaming razor-sharp finish.

It did have one downside. When sharpening bypass pruning shears and loppers the recommended sharpening grit was too aggressive and left a flat spot in the blade (even though I kept the belt moving down the blade at a continuous rate). It was also hard to reach into the tight spaces where the two blades came together.

Additionally, it did not put the “factory” sharpened angle back on the blade but rather ground its own angle. The sharpened tool was super sharp (even in the flat spot), but I would not recommend it for pruners, loppers or any precision tool where two blades come together to cause a cutting action (I’d save that for the diamond tapered rods or ceramics noted above). The power of this device is awesome but a little too much for those fine cutting gardening tool edges.

As a knife and scissor sharpener, this baby really excelled. And as a grinder it was phenomenal! With the coarse 80 grit belt, it blasted its way through lawnmower blades, hatchets, hori horis, shovels, hoes, weeding tool tines, and more.

Despite its limitations noted above, I can unequivocally recommend this sharpener. If it’s in your budget, get one. I love it and I think you will too.

Work Sharp Knife and Tool Sharpener

Part sharpener, part grinder, this electric tool sharpener excels at sharpening digging knives, scissors, lawnmower blades, hatchets, shovels, hoes and weeding tools. It's a little too aggressive for fine cutting tools, such as bypass pruners and loppers.
