hm... the description says 'chinese D2'
is there a difference in alloy like 8cr13mov is technically the chinese version of AUS-8, or is it just a questionable 'real D2' with a poor heat treat?

method_burgerA lot of it's Cr12MoV, or SKD11 with a third to a fourth as much vanadium as D2. Some of it's K110 although the standard for K110 can run just as low on vanadium and moly as Cr12MoV.
Probably some of the 'D2' knives that LTK has had tested and found as not being AISI D2 are most likely one of these steels as they're frequently sold as less expensive 'equivalents' that are also easier to machine.
More to the point -- in this case, I'm fairly confident it's not actual AISI D2 the way my Neckmuck has held up.
I cut some 3M sanding finishing sponges with mine, thin ones, maybe ten cuts in all and the next time I went to use it it needed sharpening.
The edge went on in, mm, maybe twice as long as it'd take with like AUS-8.

reswrightah, so one of those 'close enough D2' typical chinese alloys hahaha
either way, better than aus-8 so i'm sold. i have quite low standards of steel these days, my qsp penguin seems to be performing about the same as regular D2, definitely stains like D2, but i'll know for sure when i sharpen it since i have so many D2 samples from my previous job
