Support BladeForums! Paid memberships don't see ads! Hey Chris and everyone else in the gang. I have an OKT with an OD micarta handle that has brown stains on it from my leather sheath It doesn't affect function, but anyone have any suggestions for fixing it without ruining the texture of Chris' sandblast? -Ryan P.S. I also figured it would be cool to have a thread for sharpening and maintenance techniques.
