I'm fairly new to blacksmithing and knife making and I'm still trying to kind of figure everything out. On all the knives with wood handles I've made so far I have just left the wood as is without coating it in anything since I figure a coat of normal polyurethane or something will just wear off but I'm not sure. What is the best thing to put on handles to bring out the quality of the wood and keep it looking nice without wearing off after a little use? Also is staining handles a good idea before coating it in anything?
