Wallace,
This may sound odd. And definitely not masculine. But it worked well for me. I have used lady's nail file products to convex edges for some years now.
Recently, I wanted to strip the Parkerized finish off my bolt knife. I went to the local pharmacy and snagged a package of three emery type boards. They were labeled Clean, Condition, & Polish.
I wrapped the leather handle with the blue masking tape used for wooden furniture and painting, to prevent it from getting dirty and contaminated.
I went out, built a fire, grabbed a few beers, and went to work. I was actually amazed with how well this worked. I had the blade stripped and polished in no time at all. I was looking for a specific look. So I left the fuller with some Parkerizing in it. I worked the guard and bolt pommel leaving varying degrees of coating. My thought process being, I can always sand it off. I can't sand it back on.
Overall, I was extremely pleased with the results. It has the look of a well worn, but well cared for blade.
Whether you go this route or the wet sand path the blue masking tape may help your cause.
Hope this helps ya,
LV
