I was sitting around thinking about my TFK T7 Knife. Tanev Family Knives makes some beautiful hand made knives out of D2 Tool Steel. I have always liked D2, but have heard different opinions about the durability, toughness, ability to resist rust and corrosion, and all sorts of other confusion. So with that said, I figured I would play with my T7 to see if I could get a nice distilled vinegar patina. Watch as I give it a try...how do you think it will go?
