A keychain often has things that needs to be detached quickly and easily. The Kappa QR delivers the convenience and security for just that, in an entirely new way. The design is identical to the Beta QRv2 quick release - two pieces, no moving parts and nothing to break. A canted coil spring inside provides the snap-together function. The spring is manufactured by a company that is specialized in only this type of spring, commonly used for electrical and mechanical interconnects on everything from military to space equipment. Pro tip: twisting the two halves while attaching/detaching the Kappa will reduce the amount of force needed. It's a recommendation but not necessary. This Delrin version made from polymer material, so it works great when you need to avoid scratches.
