Pyro Glass Platen

[Jesse Latham]

How often do you change yours? I have been chasing scratches in low spots on the tang/ricasso areas on the last several knives. Yesterday I removed the platen and put a straight edge on it. It has a low area in the middle and both ends are worn down about .050. It is only about three years old but that is obviously too old. Jess

I change mine about twice a year. I do my contour grinding against the glass . Frank

Frank, Thanks for your reply. I will change mine more often now. Jess

i have the old steel platten for profiling an save the glass for bevels. one thingthat saves me is the fact that most of my grinding is on 2 inch wide flat ground kitche knives and that really spreads the ware load out. i replaced mine after about 3 years and the new one got a crack in it not much more then a week into use (not sure why) im still grinding with it tho since its not at a bad spot and both pieces have good bonding to the backer

I set the glass face down on a piece of plywood and heated the steel backing with a torch. The galss came off clean and I put it back on with light spring clamps in order not to force out of straight. Sure grinds better. Jess
