Don't get it dirty? That's a solution? Good luck with that!!!! Actually, solution number 4 for me would be to look at the photographs of that beautiful "Samurai" knife, and since it is already sold anyway, just get you to build something similar that has some gorgeous handle slabs that I'm certain you could fit on the full tang. Those I could clean up! I do love the Keeslar style, and you do it well.
