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.
OPERATING NOTES: Twisting the two halves while connecting/disconnecting the QR will significantly reduce the amount of force required to connect/disconnect. This is the preferred method, though it is not strictly necessary. Just pretend like you are screwing (or unscrewing) the two halves...but there are no threads of course. The twisting action pre-loads the canted coil spring and makes it easier to compress.
BREAK IN PERIOD: The sharp edge of the retaining groove (male portion of the QR) can create an excessively crisp/sharp detach on a brand new QR. The first few dozen actuations will round-over this edge. Over time, the connect/disconnect should become smoother.
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. Whenever I leave my car (hiking, taking the dog to the beach, mtn biking, etc.) I just take the fob with me and leave the rest locked in the car.
It's also nice to have my CAD dongle on a QR so I don't have to plug my entire key chain into my laptop. House keys on a QR are awesome for unlocking my shop gate...still have to drive through and don't want to take the keys out of the ignition...or when I forget something in the house after getting into the car...especially if you live somewhere hot/cold. Keep that AC/heat on while you run back to the house!
Incidentally, you can also connect the Beta QRv2 flashlight to any of the other items if you need a grab-and-go combo. Headed out on the town on the left. Walking the dog on the right :) When I lug my whole setup it's nice to have the brass Scout Hook (pictured) on my belt loop, but sometimes just a couple items in a pocket is the perfect choice.
This is a "hanging" shot. You can see how the QRs tend to nest with each other, making a smaller footprint. It's still beefcake if you have this many. I think the ideal would be one light and one QR; however, I've learned to live with this...mainly because of of the Scout Hook mentioned above :)
