That's old tech, I have one and it sucks. If I were to get a grafting tool, I would get the scionon tool
http://tropicalfruitforum.com/index.php?topic=24069.msg284751#msg284751The problem I see with these grafting tools is that you rely on the tool and begin to neglect the fact that you are losing the skill as a grafter. I graft quite frequently and I often run into various issues where I have to think on the fly and have to make unusual cuts on the rootstock or scion. When you rely on a tool, you can begin to lose the ability to adapt the graft to dynamic circumstances.
Even with the scionon tool, you may require different sized blades for smaller or larger scions where a grafting knife can handle most grafts.
