Round knife Grinding

[Old Traf]

I recently received a Jarod Todd round knife blank in AEB-L. I have been puzzling about how to grind it and not mess with the temper. If it were a fixed knife I would grind 45s then use my Fred Ro set to get close enough to go to the stones. I think I may go with doing the45s and initial grinds on the side of my Tormek T-4. Figured the water cooling would keep me from damaging the knife.

Any recommendations from the pros?

AEB-L is very easy to grind post heat treat and I do all my grinding on roundknives after heat treat. Just dunk em often as you are grinding. What stock thickness is your blank?

Stock thickness is .040 which is why I thought to grind on the side of my Tormek.

That’s perfect! Most folks that use these guys kinda want a convex grind/edge with very little if any secondary bevel. I’m making one right now for a saddlemaker in Australia. He was very specific about no secondary bevel.

Should of mentioned that I try to taper the whole blade from right in front of the handle to the edge. So its not a true convex grind per se but still shooting for a zero edge all the way around the blade.
