along with that Chinese steel
I believe Sal stated this was a new, or new to us steel not used before. If Sal thinks enough of it to make a mule out of it I'm looking foreward to working out this mule. I don't know the chemistry of it, which would at least tell me what kind of steel it is, but I'm ready for it, as well as the ZDP, and S90V mules.
I'd love to see the ZDP hardened a bit higher than the folders, and it can take it. This is, Imo, how to see what the steels are really capable of, and they don't need to have a toughness/not pushing it type heat like the folders need due to their use from everything from prying ( then complaining), to people cutting wires and nails with it (Vivi!

) If someone batons a muleteam through nails, sticks it in the wall, jumps on it and breaks it that's testing, not proof that spyderco maskes lousy knives.
Actually, Vivi is one of the best testers we have, nevertheless I'd love to see ZDP at RC66-67, to see what it's capable of.
S90V, it matters not so much if it's RC57 or 59-60. ( S110V might be different in that respect)
Sal, turbocharge ZDP for us....more than normal I mean.
