Weaver chisel grind *PIC*

Bill Tindall, E.Tn.
Over on the Lathe Forum they speak of this named grind and that to describe profiles on the end of their cutting tools. Why not here.

David introduced us to the idea of a tiny convex bevel at the end of a chisel. This idea settled in fertile ground because I had already heard of the merits of this profile to enhance the durability of knives.

The chisel is a Narex, available unhandled for less than$10. The Narex handles are crap but can be readily made nice by chucking in the lathe. The shaft is useless for dovetails but can be made useful on a grinder. The steel comes with a story about nitrogen that sounds like marketing. It is not. A metallurgist told me the process makes very good steel. Used as I typically prepared a chisel I found the edge to be as good as Two Cherries and way better than Sorby. But it gets better!

I sharpened this chisel at 30 degrees, and added a tiny convex bevel at the tip. This chisel has chopped out the waste for 5 drawers and it is as good as when I started. I am not accustomed to this edge life for this task, especially on an inexpensive chisel. I did not notice a loss of penetration ease.

I have concluded this convex edge idea has merit for a chisel used this way.
