Jason, ironically the edges have been getting thicker and thicker, but just in the middle. When my grinds looks more like round grinds rather than flat grinds, that's when I found out my platen was totally dished out! That happened much faster than I expected. My latest knives have taken twice as long to make because of correcting that dishing, and I thought it was my Grind Fu was just getting worse. Stupid platen!
