Yes I meant liners Dan!
I like to use g10 now because they are absolutley no question impervious to water, solvents whatever, and I can get them in many differnt thicknesses. I have been using black ones that are .014" thick, so it is not too much, more for an accent. I used them on a knife that I parkerized, which had OD green G10. I expected the black spacer to disappear next to the black steel, but it actually looks very good, nice and clean. And in that instance I was using only for thickening the handle!
Sorry did not mean to write a book!
