Clean cut that doesn't crush the cambium
I've used the best when it comes to bypass pruners. They all tend to dull a bit which causes the underside of the bypass to crush the cambium. Since this has two blades you don't have that problem when you push the limit to 1". The question I have is the quality of the blades. I could tell the cut wasn't as smooth after several cuts.
One use cleared my concerns
I was looking for a pruner that didn't crush the cambium of cuttings that I take for propagation material. The cut is slightly tapered to a V shape, but I quickly go back with a sharp grafting knife and make one more quick and clean cut to get a completely flat cut. Overall, these are great pruners. Comfortable, heavy duty, and they don't crush the cambium of your plants like the Felco #2 that I own.

Great for Grafting
I had been looking for something to cut the tops off my rootstock without damaging the cambium layer below and my Horticulture professor recommended these. They have helped to make cleft grafting of camellias much easier now that I don?t have to worry about damaging the cambium layer. I think that this tool is a very useful addition to a grafter?s toolbox.
