I can honestly report that the Radius Root Slayer Edger is the BEST garden tool I have reviewed. I didn’t know its “parent” – the Root Slayer – was named the Winner of the “2017 Green Thumb Award for Most Innovative Garden Tool” until I wrote this review. But it doesn’t surprise me; I am about to heap accolades galore on its progeny, the Root Slayer Edger garden tool.

I once met a Cotswolds native and superbly disciplined horticulturist who was an estate manager in the Garden State for decades. And do you know what his most important advice was? That you can always tell a good garden by its crisp, manicured edging. I never forgot that and I couldn’t agree more, so I was eager to put this edger to the test.


The Radius Root Slayer Edger arrived neatly packaged, with all blade edges safely covered. Just unwrap it and it’s ready to go.

About the Root Slayer Edger


With a carbon steel blade and shaft, o-handle grip and bright red color, it’s hard not to notice the Root Slayer Edger.

Weighing in a 4 lbs. 8 oz., this isn’t a lightweight tool, nor is it uncomfortably heavy to use, even for extended periods of time. The weight is largely due to the fact that the blade and shaft are both made of carbon steel, making it extremely strong and built to last.

The shaft is encased in polypropylene so it won’t rust or get dinged up, and it’s easy to clean. With the blade included, it reaches a total length of 39,” which is comfortable for most people. But if you’re on the taller side, there’s a longer version (the Root Slayer Edger XL) that’s 52.5” long and has a straight handle instead of the O-handle grip.

Solid Construction

The edger is solidly-constructed. This is not a product aimed at the weekend gardener, although its streamlined, lipstick-red, Ferrari-like good looks will surely inspire neighbor-envy and it can be easily used by a beginner.


To test the durability of the Radius Root Slayer Edger, I and my team (I own a garden design firm) put it through rigorous testing during our regular horticultural work – we’re respectful but unforgiving in our product use. I’m thrilled to report that the Root Slayer Edger over-delivered.

Patented Ergonomic Handle Grip

The ergonomic design of the Radius Root Slayer Edger incorporates an O-shaped thermoplastic elastomer grip. The patented O-handle is a signature design feature on Radius Garden tools; it’s supposed to offer four times the gripping surface of traditional D-handle tools and provide additional leverage while reducing hand and wrist stress.

I like being able to hold it in whatever way is most comfortable, depending on what I’m using it for, instead of being forced to hold it in only one way (as with traditional handles). Plus, the round handle is accommodating to all size of gardeners — big men and petite (but strong) women, like myself. I never had the sense that the Root Slayer Edger was out of my league.

Unusual Blade Design

The tempered mid-carbon steel blade is 6 inches long and 10 inches wide at the top of the step.

What makes the Radius Root Slayer Edger so unusual is the shape of the blade. Instead of the usual half-moon shape, it has sharp, serrated sides and a forked point at the bottom. With those two innovations, the edger can cut through most roots that get in the way of an otherwise-perfect edge. Just step on the generously-sized top edge of the blade to gain added power if roots don’t readily yield. The round handle makes it easy to rock the blade from side to side, creating a sawing motion the bites through soil and roots with little effort.

Multiple Uses


Ready to make a cut in the turf.

I must confess, I love the Radius Root Slayer Edger so much that I use it for other garden tasks, including heavier weed clearing, such as when we’re starting a new garden bed. I can kick in the edger’s blade to readily slice through the plants and their roots, making it easy to pull them out. It’s a sleek, easy to use, time-saving workhorse.


The Radius Root Slayer Edger comes with an unlimited lifetime warranty for as long as the original purchaser owns it – provided that it’s used for its intended purposes and only for normal residential use. In the unlikely event that it breaks, Radius Garden will replace it. You can find their warranty information here.


I heartily recommend the Radius Root Slayer Edger – not only to create those crisp edges for your garden beds, driveway, and walks, but also for a plethora of other garden tasks. I daresay the Root Slayer Edger is so diverse and good looking that you can gift this to your favorite gardeners — at less than $50 it’s a value-added addition to anyone’s tool shed. Or you can hang it on a wall. It’s garden art, too.

Where To Buy

The Radius Root Slayer Edger can be purchased online for $49.99 directly from the Radius Garden website as well as on Amazon (free shipping with a Prime membership). Both the regular and XL (longer) version are available at the same price.

You may also be able to find the edger at a garden center near you but call first because it’s not yet a commonly carried item.
