Keychain Light

LRI's Photon series are probably the best-known keychain lights and for good reason. They're reasonably rugged, light, and dependable.

Tiny Keychain Light

About $25, the hearing-aid-battery-powered Firefli is really tiny.

My old standby is the $5 Fox 40 Mini with the cosmetic side plates dremeled off to reduce its size. Fox has recently released a new Micro model that features a flatter profile than my hacked version, and it's reportedly just as loud.

Handy tool

The Micra and Squirt from Leatherman ($30-$40) are pleasant standouts in an otherwise bleak sea of cast metal junk. (Radioshack also has a version that replaces the standard pliers with a wire stripper.)

Pocket Compass

My favorite is the liquid-damped $15 version manufactured by old-school knife maker Marbles.

Fancy Pocket Compass

If you insist on spending more, the $50 Traildrop II Digital Compass and Temperature Keychain offers a backlight and all the functions you'd expect from a gizmo with a microchip and an LCD.

NukAlert

$160 nuclear radiation detector that looks vaguely like a car alarm remote and sounds an alarm when it detects a life-endangering amount of gamma or X radiation. By listening to the ten distinct alarm levels, you can plot a quick course out of a danger area, or, better yet, avoid entering one.

Bob,

Where did you get the keychain that is in the picture? I didn't see any mention of it in the article and I have yet to find anything like it.

USB Thumbdrive Fill Up

Note that the USB Thumb Drive fillup appeared TWICE (pages 142 and 177). Instead of keeping outlook PSTs on your stick consider a copy of Thunderbird.
