I'm curious about what causes the difference in cutting between a hollow grind and flat grind. I personly prefer the flat grind for my knives, but I'd like to know the difference. As I understand it (I've never done one myself) you grind the hollow, h/t, and then put a flat or convex edge on the blade using the slack part of the belt. Is that right? If so this is basically the same edge as a flat ground blade, except for the cross-section of steel that's behind it. At least this is what it looks like on most of the hollow-ground knives I have. Any thoughts on this?
