I have had a couple CRK with Devin Thomas Stainless Damascus Blades. I have used them quite heavily for edc and none of them showed any wear after cutting tons of cardboard, whittling, and other edc duties. I found it easy to sharpen and held a pretty good edge and to me, felt it was basically just a fancy S30V as it performed just like it. I really did nothing with it that I would not do with my other sebenza's and mnandi's.............For a EDC user though, I would definitely go with the Stainless Damascus as the High Carbon Damascus is more prone to rust as they have to put a varnish like coating on it to help keep it from doing so, this came from Devin Thomas themselves. So when looking, I only look for SS Damascus. The HC will have more exotic patterns, but personally, they are more of the safe queen type, where as the SS os more for the User. Both are beautiful and you will read here that people edc the HC with no issues, I am just going by what I was told by DT himself when I emailed them years ago inquiring about their damascus and the differences. I dont believe that DT even makes HC Damascus anymore though, so all the recent sebenza's will definitely have the SS Damascus blades.
And the old adage when people question anything about CRK, I always tell myself, if its good enough for Chris Reeve, its good enough for me.
So either way, wether HC or SS, you will be getting the highest quality out there.
