I like that a lot. Nice work.
I've blackened tattoo machine frames by quenching in used motor oil as mentioned by spike. If you dont want to temper the steel to brittleness you dont need to quench straight from the forge. An hour or so in a hot oven is usually fine, & used deisel oil works better than that from a petrol engine.
