Make sure you do only side grafts and similar ones as this tool cannot properly do cleft type cut. You cannot slice cut like a Scionon tool, you have to c
rush cut which is a no no for soft scions but with the sharpness of the utility blade, it might work.
See below.
This is what I have and tried and given up. Got them at HD and they come in 2 sizes:
They are not meant to slice cut things, so a
crush cut is the only way possible to get a decent size cut:
Next to a Scionon, you could clearly see that the Scionon opens much wider and with the groove to hold the tip of the scion, it could easily slice cut it.
