Well tastes do vary, so if he likes that look he should pick it up. One plus if it is a vapor deposited finish is that it will be very wear resistant. Both Titanium Nitride and Titainium Carbide produce a very thin layer of an extremely wear resistant ceramic. I've used these processes for years on swaging tools for fabricating steel tubing and they only fail when the softer substate breaks down and the coating then fractures.
