A.M. Leonard has been around since 1885 but even though it is an industry leader in the horticultural field, many homeowners aren’t familiar with the brand. With the ART17 double cut pruner, A.M. Leonard introduces a style of pruner that’s most likely unfamiliar to the typical American gardener, though it has been used in Europe for many years. It’s neither a bypass pruner nor an anvil pruner. Instead, it’s a cross between the two, with two sharpened blades that come together as the final cut is made.

CUTTING BLADES MAKE CLEAN CUTS

The blades are made from 5/8” hot-forged high-carbon Swedish steel, giving them a very sharp and long lasting edge.

The greatest advantage of two sharpened steel blades that come together is that they make very clean cuts without crushing the wood. As a result, cuts heal faster and cause less stress on the plant and, consequently, less risk of disease.

The cutting precision of the A.M. Leonard ART17 was excellent and left no rips, tears, or crushing of the wood. With the fine tips, I was able to make perfect cuts at the intersection between the branch and the limb, known as the “branch bark collar”.

Another benefit of the double cut design is that it makes similarly clean cuts regardless of which hand you hold it in (lefties rejoice!) and which direction you make your cuts from.

CUTTING PERFORMANCE IS DIFFERENT FROM BYPASS PRUNERS

The cuts made by the A.M. Leonard ART17 are significantly different from the typical bypass pruner; I noticed a distinct ridge in the center of the branch being cut.  But, unlike some bypass pruners, there was no pinching of the outside bark by the counter blade (some bypass pruners can leave an indent on the outside of a branch’s bark, which can slow the healing process).

Cutting with some bypass pruners can leave less than a clean cut.

Not Suitable For Cutting Soft Material

The double cut pruner design originated in the orchard industry, where it is preferred for it’s extremely clean cuts. These cuts don’t damage bark or crush cut stems, and it is an excellent design for cutting through woody material.

The pruner does not work as well on softer stems, such as when deadheading or cutting back herbaceous perennials. So this pruner isn’t one that would be used for all your pruning or cutting tasks in the garden.

CUTTING HEAD HAS LOTS OF MICRO-ADJUSTMENT

The cutting head is much the same as a bypass pruner, with a central bolt to secure both blades. The A.M. Leonard ART17 Double Cut Pruner has a micro adjustment screw and hinge mechanism that makes sure the center bolt will not move while cutting and helps with micro-adjusting the blade tension for the perfect cut. There’s also a micro-adjustment screw that protrudes from the handle that sets the proper spacing of the cutting blades.

Multiple fine tuning adjustments allow for clean cuts.

COMFORTABLE HANDLES AND SECURE LOCKING MECHANISM

The handles are extremely comfortable. They are made with a composite material and incorporate two ridges near the head of the pruner that make for a perfect hand position.

The pruner locking mechanism is a spring loaded swing bar at the end of the handles that holds the handles securely in the locked position. When the pruner is open, the bar can be swung and locked under the handle (parallel to the handle) or left sticking straight out the back of the handle. Don’t leave the locking bar pointing toward the other handle or you’ll end up hitting it with every cut.

DIFFICULTY IN CUTTING 1” THICK MATERIAL

A.M. Leonard claims that the ART17 Double Cut Pruner can slice through 1 inch material, but I was able to cut only part way through 1 inch medium soft live wood. There may be softer woods like canes, stalks and soft vines that the pruner could manage a 1 inch cut. The largest cut I was able to make in a medium soft live wood was ¾ inch. This cut was clean, just like all the other smaller diameter cuts I made.

NO REPLACEMENT BLADES

The head is an integrated one-piece design so there are no replacement blades available. And, as with all cutting tools, the blades will eventually need sharpening. Just looking at the tolerances of the blade closure (they have to fit perfectly together to make a clean cut), I think I’d be hard pressed to sharpen this pruner without causing a deformity in the blade, thereby causing a ragged cut. If you do want to try sharpening the blades, be extremely careful. I’d use a fine grit diamond hone and gently stroke each blade (being sure to maintain the edge angle) an equal number of times.

WARRANTY

A.M. Leonard offers a 30-day complete satisfaction guarantee. Other than that, it only warranties its products to be free from material or workmanship defects.

RECOMMENDATION

This is a very different type of pruner from what you may be used to. I was most impressed with the fine cuts that it made with no damage to the bark. This is a quality pruner that does not skimp on materials and workmanship. The few very minor drawbacks are a handle locking mechanism that could get in the way of the two handles closing, the fact that it only cuts through ¾ inch wood (rather than the 1 inch diameter claimed) and that it’s intended for woody stems only. All things considered I would definitely add a pair of these pruners to my gardening bag.
