I have the Rat-3's in D2 as woods knives.. and must have gotten a bargain, considering how happy I am..
They're not precisely what you want but they make a strong arguement for D2 steel. I *really* like steel that doesn't require sharpening often for woods walks. I can spend hours if necessary sharpening with a diamond lap or a buffing wheel, if it will STAY sharp for a while.. D2 will definately Stay sharp.
It's odd to me there aren't more manufacturers using it, considering how well it handle rough work. That short 'field' knife likely will amaze you on performance. recommend you touch it up at home, first.. and don't trust the edge 'out of the box'.
