I invented this in about 1995, and you can buy them here if you don't want to make them...

the only difference is that I decided to weld the chain to the sprocket. MUCH quicker to make.

i made one this weekend using a dremmel for the first time. i just drilled one hole in mine though and attached it to my keys as a badass keychain. thanks for the idea.

Very cool and for a worthy cause! I assume that a stainless chain is best. A nickel plated chain may cause skin rashes (although you may argue that for beer this is worth it). Will a regular chain tend to rust?

all that work for the champagne of beers? doesn't this sort of job call for a Fat Tire?

thats a really neat idea, you could probably mod it to allow the chain to wrap around the opener to make it fit in a pocket or use a smaller gauge chain to make it a neck ornament. keep up the cool mods
