I've been reading a lot on the subject and have referenced a couple of external sources for additional info. I think I have the process understood and would like to make an attempt at it sans-power tools. What I'm stuck on is the choice of course stone for the grinding. What would be a relatively cost effective stone for this? I'm assuming such a focused grind would dish the stone excessively, so I'm prepared for plenty of flattening afterward.
I've attached an image (courtesy of BDL's blog) annotated with my residual questions. What I haven't noted on it was a question around the "chin" of the finger guard. The chin is mentioned in several posts with regard to the subject, but I'm not exactly sure what it references. If someone can clarify that for me, I'd appreciate it.
