I know I've said his before, but you asked...

The usual suspects I carry most everywhere:

1. Victorinox Midnite MiniChamp II
2. Victorinox Money Clip
3. Leatherman Wave
4. Gerber Harsey Air Ranger II (plain edge)
5. Benchmade 100 River & Rescue (plain edge)

These are also supplemented by the rest of my collection when circumstances demand, like my SOG Access Card...and there's a whole bunch more...
