Mini quick-release that actually works

This titanium quick-release keychain is built like a tiny tank with a clever ball-bearing collar mechanism. I use it to separate my house key from a carabiner that's clipped to my shoulder bag. It takes deliberate action to detach (no accidental separations), yet disconnects smoothly when you want it to. Here's a photo so you can see how small it is. — MF
