I have an old double bit axe with serious pitting and rust. The steel looks like it has lots of little holes in it. there is some thinning around the edge of the eye and it hasn't had an edge on it in a good 30 plus years. I can post pictures later tonight as I'm at work but i was just wondering what some of you axe gurus thought about the safety of using an axe that's in such bad shape. I have done the whole vinegar soak for a few days and it took most of the rust off but there is a fair bit left to take off with a file. Lost cause? or a "who knows" till you see pics?
