I have never owned a knife with A-2 blade steel. I've heard that it is a very tough steel, but will require some care. I like a knife that has a patina, so stains won't bother me at all. My guess is that Rick will likely run them pretty high HRC like he does most other steels. Please give us some feedback on how your A-2 knife performs compared to other steels. BTW, great looking knife/sheath combo.
