nitriding

[revhard05]

has anyone every nitride,ed a blade? i would assume it would be done after all final metal work and before grips. any info would be helpful.

I asked my heatreaters about nitriding many years ago. My understanding was that the temperatures needed would adversely affect your blades temper. Also a one off would cost an arm and a leg.

but, could it possibly be a opposition to heat treating, being that no residual stresses are created with the lock of the quench? hence no need for temper

While the nitriding doesn't need HT the steel first has to be HT'd. Some of the tool steels are nitrided ,those which first are hardened and then tempered at about 1000 F. They are then nitrided. But once you sharpen the blade the nitrided layer will be removed.

right, thanks mete

isnt that what david hasselholf did? nitrided

IMHO, nitriding makes a lot more sense for adding corrosion resistance to a few steels with high tempering temperatures (e.g. 3V) than it does for edge holding. As others have pointed out, the edge holding advantage only lasts until the first sharpening.

Now thats a brilliant idea, imo.
