My first super steel was CPM440V. And my "Mule" was and still is a Starmate.
Then came CPM420V, known now as S90V and the world was never the same... ;-)
Those days CPM 3V, CPM M4 and CPM Cru-Wear got my attention when adapted to a folding platform. The Tuff, the Gayle Bradley and the Millie grey sprint run are really a joy to use and maintain to high performances.
I would love to see those steels on a Nilakka, or a Yojimbo 2 or a Paramillie or better:
on a Tatanka !!
A sprint run Tatanka in CPM M4 would be a bless from Heaven ! ;-)
