What do men want...

…in their Christmas stocking?

I am filling up a Christmas stocking for my boyfriend. He’s in his twenties and possibly the most complicated person to shop for. He likes things like video games, working outside, building things, electronics, weapons, and other standard “guy things”. He’s not a drinker, so anything alcohol related would not be appropriate.

I’m quite possibly the most inept Christmas shopper on the planet. Please help me, fluther. I know you guys have some good ideas.
