So I've been using my HD for a while now, and I've noticed a few things.
#1) I am getting a little bit of blue-ish patina about 2/3 down the blade - no idea which food product it might be from.
#2) I've noted that the knife has some "swirls" or something going on on the blade. At first I thought this was the lacquer. So I used my wife's acetone-containing nail polish remover - but didn't really do anything. It's a pain-in-the-butt to take a picture of, but has anyone else encountered this?
