The GDC Zip Light only does two things, but it does these two things really well:

1. Shine light
2. Open beer

The Zip LIght has a zipper loop attachment that allows you to attach to a zipper or keychain, but you can detach in the blink of an eye with clip.

The light is made from stainlness steel, and uses replacable lithium ion batteries to power the bright LED.

The Zip Light is only $8 and carries Gerber's lifetime warranty.
