I have an old broad axe that I picked up on ebay that turns out to not be useable. If looking straight into the blade edge it has a large bow directly in the center of it. I dont know why it is like this but it definitely makes it not a good working axe. It should be flat like a chisel edge , but it is more like a gouge shape as it is now.. Anyone know why this would happen and if there is a way to correct it. I thought about trying to even it out but this would be way too much material to work off. Perhaps it is just one to hang on the wall? tb
