On my journey to becoming a gadgeteer I came across these quick release keychains.

With a simple addition of a quick release mechanism, a simple keychain becomes a utility belt.. err.. ring. You could just keep attaching gear to it which you know might come in handy, like a light, separating different set of keys (house keys, car keys), heck I'd attach one to my trusty Leatherman Squirt if only I can get a spare! Cause I don't feel like just leaving my one and only Squirt on a keychain. (It's hard to find a replacement cause our Leatherman distributor doesn't seem to think it's a good idea to bring in what I'd call the BEST DAMN pocket sized tool ever!)

So when I saw this in ACE Hardware the other day.

A Niteize S-Biner which is essentially.. a key chain with 2 quick release ends.I don't really have a specific use for it right now but I thought I should just get one and keep it around.
