I bought the root saw, hoping I could cut out "sucker" growing around my favorite fruit trees, get enough root so that the small tree could make it on its own, replanted close to the mother tree. Later I intend to graft scions onto the small new tree. The root saw worked amazingly well. I was able to cut down next to the sucker tree and detach the shoot from the mother tree. Hope the process works, but the saw is much better than a shovel or spade for this purpose.
