Now THAT should look nice.
You could always do what I call rust bluing, or it may more accurately be referred to as Browning(?)
Wet down the blade, or just shove it in damp ground for a couple hours or maybe even a day. Let rust form on the steel, then rub it off with a scotch brite pad, repeat until you get a finish that will almost not rust at all.
Thats an interesting idea. I will have to test that on one of my other knives. Makes sense though. Bet it looks cool too.
