/diy/ - Do It Yourself

I only cut 50% of the primary bevel before heat treat - mainly because I read somewhere that a if it were ground all the way, the thin cross section could be burned out during heat treat.

I used my preferred sharpening method (an upside down belt sander) to clean away most of the carbon buildup and also to grind most of the primary bevel. I eyeballed 30 degrees. It doesn't matter that much. I still have about a mm to go before I hit the apex.

I have a special technique for using a belt sander to sharpen seriously damaged chisels and knives without bluing the steel. It's pretty much the best sharpening method and I've tried them all.
