Some talk in the gunsmithing forums has gotten me thinking (scary!) about rust bluing a knife.

What would be the best do-it-myself-at-home finish for a non stainless steel knife? I was thinking about trying to build one from a kit and was wondering about a finish to reduce corrosion. It would be a fixed blade hunting/caping knife for deer and hog sized animals, and usually be cleanable within a few hours after getting bloody.

Would rust-bluing be enough? Seems popular on rifles seeing similar conditions (except for the blood part).

I blued a Schrade Little Finger as a preemptive measure years ago. Seems to work well.
