I've removed the coating on several pocket-clips (Spyderco, Benchmade, Kershaw, etc.) and I thought this coating on the American Lawman was going to come off easily since it scratched so easily, but apparently they've either improved their coating or I way over estimated how easy it was going to be based on reading about how others had removed it from theirs.
I tried several different chemicals, and still had to take some 800 grit (and in some places, 600 grit) to it. Since it's going to be a user, it doesn't really bother me that it now has sanding lines on it (I don't want it polished), but I may try the home-made stone-wash now just to do it and see how it looks.
Also, interestingly enough - I have an issue with mine where it (every now and then - not consistently) is really hard to depress the lock-bar (like it's catching on something). Upon taking it apart, I figured out that the back-spacer is aluminum and the spring was digging into it a little bit and getting stuck and "jumping" out of the spot it dug. I sanded/smoothed up the spring-bar and where it was making contact and it fixed this issue.
Also - my knife has both (what appears to be) phosphorous-bronze washers as well as a paper-thin set of what I'm guessing is Teflon washers up against the steel. This struck me as almost opposite of what you would want (phosphorous-bronze should be up against steel right? And Teflon would make a good layer against the G10 since there are no liners).
It's a good little knife and I'll say that if the coating has been improved over the older coating, it was done well enough that I would advise caution before tackling the job of removing the coating.
If it's the same old coating, then maybe I'm just a huge wuss
