Depends on how deeply the etching is.....it can vary from simple hand sanding if the etch is very shallow, to requiring a complete "regrind" if the etch is deep. Unless you're versed on blade finishing, I would recommend contacting the maker, and seeing what he/she would charge you to do it. Depending on the type of configuration (guard, handle, scales, type of grind, etc.) it could be either an easy job, or a real tough one.
