Is there a way to restore Teflon Coating in knives?

[TheseusTheDestroyer]

Yes I'm talking about a Cold Steel Recon 1, the old Ultralock model. I have a couple that are in excellent condition except for a few scratches on the blade because that Teflon comes off so damn easily. As some of you might know, this model knife can be pretty expensive if the conditions of the Teflon are good. and I would like to touch mine up and keep them in display. I know there's a way to do it with cookware and other things that use Teflon but i'm not sure if I would use the same method for a knife blade. Please help me out if you know a way or at least think of something that's worth trying. Thanks guys!

A cheap way to do it would be spray painting the blade with the desired color and then heating it an oven for an x amount of time. I cant remember how long but I know it is possible. Not the strongest of coatings but for display it should be okay. There might be some YT videos on it if you know how to look.

I found a video on it but the guy was coating a gun frame. Won't baking it ruin the heat treat?

There is no home-brew method to apply teflon, as far as I know. The surface-preparation and processing to get it to stick to the substrate is extensive in the factory setting.

I'd be tempted to strip the blade, and GunKote it myself, if you really insist on a coating. The temperatures used to cure finishes aren't high enough to start drawing the heat treat, that doesn't happen until ~400F, and most finishes cure around ~200F, as I recall. Could be wrong there, but it was well below tempering temperatures.

I saw this video on youtube:

in this video the guy sprays three coats of this Teflon stuff on the gun part and then he sticks it in an oven at 300 degrees for half an hour. I'd like to think this would work with a blade except of course the Teflon on the blade (unlike the gun) would receive a lot more friction due to cutting, stabbing and other things you don't usually do with a gun (LOL) so I'm afraid the coating wouldn't last long, and then i'm back to my original problem of the coating coming off too easily.

you dont think 300 is a little close to 400 in temperature?
