How do I tell if a blade is black oxide coated, titanium coated, paint, or what?

on: August 31, 2018, 06:42:53 AM

I have a Chinese knife with a black blade. The handles are obviously anodized aluminum, but the stainless blade is also black, as are the tools. It's a somewhat glossy black, but doesn't feel oily. It doesn't quite look like my black oxide Gerber, which admittedly is very used and worn, and has a matte black finish. The blade's coating has some scratches where I slipped with a diamond file, while sharpening the serrations. Otherwise, the coating holds up well. The bitdriver sees regular use, and it is not showing any wear yet. What would this coating be?

it's paint, almost sure about that

probably some kind of teflon based coating, based on its price, country of origin and similar tools I've had, seen or handled

not in the same level of resistance to scratching as better ones,

like:

Blackwash
Black Oxide
TiNi Coating
DLC Coating
Cerakoating

Okay. My CRKT ZillaTool and Guppie appear to have the same stuff. I'm thinking Teflon coating.
