don't do yourself that favor! <img src="/ubbthreads/images/graemlins/doh.gif" alt="" /> (if anything pm Dan himself and ask him)

any factory coating is better than "home-brew" even worn, it still protects the blade (and worn looks cool, no other blade looks like it)

modifying anything on your blade will most likely void your warranty, but hey it's your blade for sure but I wouldn't expect to have the warranty still valid.
