Here's a keychain set I've been carrying for awhile. No particular purpose or reasoning in the component choices. Most of the stuff was just lying around, so I put it together.

Carabiner: http://www.backpackinglight.com/cgi-bin/backpackinglight/ursalite_micro_carabiner.html

Smallest full-functional wire-gate biner I've ever seen. Held my 20-pound food bag with no problem.

Flashlight: http://www.brightguy.com/detail.php?Sku=STR72101

I didn't like the hearing aid batteries at first, but this turned out to be a great little light. Rugged and compact. No argument that the ARC might be better, but this works too.

Whistle: http://www.iboats.com/mall/index.cgi?pro...rt_id=781296703

This is a great little whistle. It's as small and flat and loud (based on subjective testing in the car). Most important, it has a hasp lug that takes a split ring very well. Ideal for a keychain.

Fire: https://scoutnet.scouting.org/BSASupply/...;amp;item=01167

I put the striker and rod on separate split rings so the striker can be used just by uncliping it from the carabiner, rather than having to work it off of a split ring.

A more complete, better thought-out set of gadgets is on my actual keyring.

- Larger, cheapo wire keyring carabiner
- 3 keys
- JetScream whistle
- CMG Sonic (white) AAA flashlight
- Photon II (red)
- BSA Hot Spark (on two split rings)
- Small spy capsule with some pills (as an excuse for carrying it) stuffed with cotton for tinder

Just some grist for the mill...
