Hi guys, I think I'm getting hooked on this hobby of yours. I have 2 knives ready for heat treating (happening tomorrow or the day after) and a set of carving knives well on the way. I'm already thinking about the next knife. I would like to make a nice camp knife for myself. But I want the blade to be blackened. It doesn't have to be shiny or dark. I'm thinking a matte dark grey finish. Ideally something that will help prevent corrosion, as the weather here can be pretty moist most of the year. Blade will be O1 steel. I've been considering parkerizing, but I haven't made up my mind yet... Anybody have a secret recipe that they would like to share?
