I am making a combat knife, double edged, out of a Nicholson file. firstly, when I started knife making, this was the one I vowed to make perfectly one day to honor the person who got me into knife making, so I am very committed to it being the original design if possible. Whilst looking for advice about tempering it after cold stock removal working, someone pointed out a flaw in my idea. that flaw was the tang, I want to make a full-tang handle and have a diagonal cut white to black Garolite scales. but I acknowledge the rust prone nature of that design. how could I make the edges very rust resistant?
