Try using a medium slip stone or hard Arkansas instead of the diamond. A
course diamond is 220 grit which is not course enough to raise a good burr.

My Kelton Hollower is beginning to lose its edge. I keep touching up the
edge with a credit card-sized diamond hone, but I keep thinking its gonna
need grinding. I'm using the one with the most severe curve. Anyone ever
try grinding one of these things? I'm thinking I'm gonna have to give it
a
shot, but I don't wanna ruin my tool.
