I have had this question myself more than a few times, wanting a black hook but it not being available in the size/shape. Has anyone ever tried to blue hooks? would it work? dipping them in the ,I think, Jax Iron blackener or whatever the product is called or would it just not work on the materiel that hooks are made of? I have thought of trying it many times but never have gotten motivated enough to go and but the blueing stuff.
