This hand clipper is a really cool ergonomic innovation. It uses an ingenious gear design to easily slice off sticks that are 3/4 inch in diameter. As you squeeze, the bottom handle rolls slightly and this motion leverages the power in the scissor cut. I find I can now tackle stuff that ordinarily I would have had to run back to get the larger pruners for. Your Felco pruning clippers will last you a lifetime, but as my grip wanes, I find I this lightweight Fiskars pruner is the clipper I grab first.
