    The avatar is the Steelmark created by AISI back in the 60s. Depending on who you ask the three astroids represent different things. I like the idea of the three components used to make steel. Yellow - coal, orange - iron ore and blue scrap steel.

    Speed Star® is the trade name used by Carpenter (CarTech) for their version of M2 HSS. Back in the day, every producer had a trade name for their tool and high-speed steels to differentiate them. Now that they are more of a commodity, the names don't mean as much.

    Avatar looks like an NFL football team's logo, but I could be mistaken!?

    I'm a structural engineer so I have a lot more interest in the steel industry than in the football team.

    Ah, so you help build things! That's much more beneficial than watching 22 millionares run around for an hour!

    yes ! That's why I asked ! M2HSS on modern folding knives is one of my traumatism ! :-)

    Welcome, HSS and thanks for the input. If I am ever able to get and try CPM Cruwear out I wilp likely jump at the chance though I have 2 excellent M4 knives (Manix2 and Mili). Sadly I have barely touched the Mili as I can't legally carry it and want to baby it (though I uave used it a bit just to enjoy the quality and capability). I do want to maintain a fair amount of condition and value but I use all of my knives so I exect it will break in a bit eventually. It really is my #1 grail knife so I do have a bit of pride and reverence for the engineering and design.

    I've used my CruWear Mule quite a bit at Scout Camp and yardwork. It has impressed me with its edgeholding. I haven't really "stress tested" it in the field - but I haven't babied it either. It also hasn't developed a patina yet, either.

    Here's a shot of it after I sent it back to Spyderco for re-heat treating and put brown canvas micarta scales on. I sharpened it up using a 35 degree back bevel with a small 42 degree edge bevel. Seems to be very stable at that config.

    I have a second Mule that I put black linen micarta scales on. This one is used by my son primarily... The pictures of this one are pre-sharpening, as well. It has since been configured to the same 35/42 edge as my other one.

    Need some shots after cutting citrus, or spreading mustard, or things like that?

    I haven't noticed any staining of note on mine, but the blade has accumulated a whole bunch of scratches.

    Vinegar, lemon juice, mustard... Nothing is triggering a patina. I had the same (non) results with CPM 3V.
    The EDC tests go on. :-)

    People must eat some interesting mustard for it to need spreading.

    Mine has a little patina from cutting a steak. I just wiped the blade off and forgot to wash it from a couple hours. When I remembered to wash the blade I had a nice little patina going on.
