I recently had a bit of engraving done to a pistol... It is great work and all done by hand (not machine done). The issue is that it's kind of sharp... Like not totally smooth... You can feel the edges and it just feels odd to the touch. Without emailing my engraver to ask for suggestions and perhaps offend him, does the Board have any ideas? I was thinking maybe the finest grit sandpaper but I am not an expert by any means. My goal was to perhaps have it look like it was done ages ago.Thank you.
