no,but i have been really trying to on my ASH-1.

the coating on these busse kin knives is the longest lasting i have ever seen and i just want to see how much use it can take and so far i'm just left frustrated since i use the hell out of it and the coating is still there.

i'm sure if my DFLE had a coating it would be gone by now though.i love that used look when the majority of the coating is rubbed off
