Kappa QR Fuse3D

Quick, easy, secure, stylish Marketing lingo for "it's freaking awesome!" Just like a flashlight, sometimes you have things on your key chain that you may need to quickly and easily detach. That might even be your actual keys! The Kappa QR delivers convenience (and security) in an entirely new way. This design is identical to (and compatible with) the Beta-QR v2 quick release design. A proprietary "canted coil spring" is used to provide a "snap together" action: two pieces, no moving parts, nothing to break and the spring is replaceable if that's ever needed. The spring is manufactured by a company that specializes in only this type of spring. It's commonly used for electrical and mechanical interconnects on everything from heart implants to military electronics to stuff that flies in space. It should be adequate for your house key. This is my current key chain; it's pretty beefy. That's a lot of brass. A couple of notes: I have taken to putting my car fob on a separate QR. Wheneve
