I think 12C27 is a very good choice for this knife. BRKT's 12C27 is said to behave a lot like their A2, with the added benefit of it being corrosion resistant. Most of the 'high performance stainlesses' would chip where 12C27 should not. For a 'hard use' stainless, 12C27 is hard to beat (not counting H-1)!
Bark River's 12C27 is excellent. It does perform similar to their A2 and can take a wicked fine edge. I use this steel in my Bark River Chef's knife.
Very smart.
I am not a fan of the thumb 'grooves', but that is just a personal thing.
I think they will do well with this knife.
If you want one of the weirder options, get it now, I bet that they will cut back to fewer options once the market speaks.
