Hey all, I have a wooden handle Rapala Fillet knife like this one: http://www.basspro.com/webapp/wcs/stores/servlet/Product_10151_-1_10001_15922____SearchResults Its a good knife for no better than I am at filleting fish. I've used the knife quite a bit, and the wood handle is starting to soak up water and fish smell when i use it. I think it has some sort of Poly coating or similar on it, but that's starting to wear. Should i get some butcher block mineral oil and coat it, or put it in bleach water for a few minute to kill any fishy bacteria? I try to wash it and dry it immediately after use, but its still discolored until it dries out good. I dont want a new knife, cause other than this, its in great shape. What are your thoughts and suggestions?
