I bought an old knife, the previous owner botched up the blade. The sharpening was done so bad there are sections that look like a one sided knife blade and some that are sharpened on both. I can usually get a good hone on a knife if its been factory sharpened and then I take good care of it. But I'm not sure how I would restore this blade to a factory condition. I'd normally contact the manufacturer but they are no longer in existence.
How can I get my knife back to factory sharp condition? I'd like to get it ground down, how do I do this? What is the easiest way to do this?
