According to the sales pitch on there website they use a "cryogenic hardening process" to make there blades last longer than the competition. Depending on the price of the blade I would say to give it a shot. On this ( http://www.knifeforums.com/forums/sh...hp?tid/802768/ ) site the people seem to think that there is a certain temperature the blades need to be hardened to too be effective. I'd be skeptical of the actual process milwaukee is using to "harden" these blades and whether or not they are actually cost effective.
