David- You can imagine if someone used something like a billet of 154CM (crucible melt) steel for a crank. Would wear out the cutting tools pretty quickly. All depends on the steel you use whether forged is tougher or not. 154CM is an aerospace steel used in turbine engine parts and knife-making, Rockwell 62-63 in toughness.
Billet turned cranks were always a Ferrari selling point in the olden days.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
