looks like a good knife. if it works for you that is all that matters!
I don’t graft, although I will be trying this year with a grafting tool (not a knife).
I have a small collection of pocket knives, and I like to use this one in the garden when I need use of a fine task where my mora bushcraft would be overkill.
Based on most people’s description of a sheepsfoot blade with more stiff handling characteristics, it might work well for grafting. just a guess though.
