Can anyone tell me what is the best way to finish a wooden handle? I have tried oiling it but after some use it gets pretty nasty looking and needs to be sanded more to clean it up. I have sprayed a clear sheen on some and that seems to look good. But, doing that I also get the spray on the metal between the two handle halves and that will probably chip off with use and look like trash again. I am looking for a way to preserve the nice look of the burl. Thanks
