Onetone, I have seen this as well. I have an OMP Sektor II riser that is half G10 or the likes, and half wood. It has developed the "catch edge" where the wood has shrank etc and the glass did not give. What I want to do will be a very small piece and very small area.
My Ammonium persulfate will be her tomorrow to try the etching. The wire inlay idea is also interesting as well!
