Got this as a gift second handed and would like to sharpen it and make it usable again. The serrated top part started to just break off, so I am cautious about potential metal parts in my food. Any tips welcome, thanks.
I mean, you can always re-temper as well, but now I do understand that that is going well beyond the pale of just grinding the metal down.
That being said, depending on the knife, it could have a relatively thin, harder edge and grinding it down could go into the softer core metal.
