Created with a back to basics approach, the HANDGREY Quick-Release Titanium Carabiner Keychain is the final product after 102 iterations. Each keychain is cut from Grade 5 Titanium and designed strictly for keys, and not climbing (although it can bear a maximum weight of 25 kilograms). It has a dedicated quick release design that lets you easily attach and detach key rings without having to unhook the entire thing off your belt loop.

All the early bird specials on Kickstarter are gone, but you can still pick one up for $55, with deliveries slated for November.

Price: $55+
