HSS forges beautifully when at temperature, though. It becomes
"super plastic" at forging temperatures. This is a phenomenon
that occurs in ultra high carbon steels with extremely fine
grain structures. I used to forge M2 lathe bits into plane
irons. It was a breeze. Grinding them to final form was
another kettle of fish.
