The KeyBiner Carabiner Combination Keychain & Multi-Tool ($35) takes the standard carabiner to a whole new level. It features a key retention system on the back that allows you to organize up to 14 keys. The carabiner itself contains six different wrench sizes, a pry bar that can also act as a standard screwdriver, key ring holes, a 1/4″ screw bit driver, and of course a bottle opener. There is also an option for a USB thumb drive. The KeyBiner basically literally has everything but the kitchen sink. Available in aluminum and titanium, you can order from their Kickstarter campaign right now.
