My every day carry (other than my wallet) is usually a Leatherman Supertool on my belt, and a Schrade Tough Chip in my front pocket. I'm usually not far from a PSK, but for those times when I'm not, I wanted to start the habit of always having a small one on me. I've decided to go with a standard Altoids tin (1.76 ounce size) over other containers for several reasons:

Fits in a pocket of just about everything I own.
Easy to replace if lost, worn or damaged.
Inconspicuous if taken out in public.
Won't squish the contents in a jean pocket.

That being said I wanted to ask everyone what they think would be the ideal contents of this tin combined with my other EDC?

Thanks,
Paul
