What Steel is Used in the Leatherman Surge?

[lava_lamp]

I searched the site, but couldn't find a posting that addressed the blade steel in the Leatherman Surge. I have a version that I bought last year with one-hand opening, locking blades.

Anybody know the steel used? Just curious...

The blade steel is 420HC. This goes for the Surge, Wave, Core, Blast, Fuse, Kick, Pulse, Supertool200, Supertool, Skeletool, PST II, PST, Squirt, Juice, and Micra.
