What kind of gift you would give to someone like this?

I'm a recently divored, about-to-graduate law student. I left the Mormon church (cult!) and my wife left me and took my son. That was January. So it's been a tough year. I'm trying to stay positive and I like the following: history, vikings, celtic stuff, dragonball, mythology, books, martial arts, philosophy, anime, manly jewelery / trinkets, fancy tea, fancy scotch, music (trance, electronic, jazz, classical, rock, and metal), candles, knives, weaponry of any sort really (no guns).

Not me, doing a secret santa thing, don't know what to get the guy.
