Greetings all! I spent a little time on the road yesterday and the craziest thing popped into my soon to be senility laden head. Does anyone or has anyone tried to chemically sharpen a knife blade? Fishook manufacturers do it. Drop your old worn files into a vinegar bath for a couple of days and say "Make it so #1", the next thing you know your files are usable again. Does this process transfer to our beloved blades successfully? What say ye?
