Deflecting vs. letting go ()

Bill Tindall, E.Tn.
Manganese is primarily responsible for toughness. I suspect the Cr is there for wear.

That said, if the test is bashing the edge into maple with a mallet the force resisting Penetration is irrelevant. Bash harder. I can understand that someone that carves for hours a day would be interested in force to create a shaving, but not someone chopping dovetail waste. It takes no more than "love taps" to drive a chisel through a poplar drawer side.

If I need a microscope to see damage at the edge this damage, whatever kind it is, will have no effect on my use of the chisel to remove dovetail waste. What is important to me is how long before I need to sharpen, and when I do, how much effort will it take to correct damage.

David is the only person I have encountered that prefers chipping to folding for edge dulling in a dovetail waste removal operation. The reason for preference is that less metal needs to be removed to correct folding than to correct chipping. In fact I often just rub the edge on a hard ARK stone and it restraightens enough to carry on.
