Easy DIY black oxide!

I had no idea how easy this actually is. Simply heat up your tool with a propane torch until it starts to change color. It doesn't have to get red or even orange, but you will notice a change in the sheen of the tool. Make sure that sheen change is uniform. When the tool seems ever so slightly orange, plunge it into used motor oil. Wait for the smoke to stop and the tool to cool, take it out, and BAM. Black oxide.
This works great for small, short tools that can be evenly heated. For longer tools I think I'd need a rosebud tip on my propane torch to be able to get an even heating.
The results are pretty good. This was originally a silver SOG 1/4 socket holder which I dremeled and filed to fit an MP600. Once it fit, I heated it up and plunged it into motor oil, not really thinking it'd work all that well.... but the results are exceptional!
