The WTF Mini Titanium Keychain is a masterfully simple and elegant design that takes a diamond-shaped piece of titanium and turns it into a multi-purpose tool that is strong, secure, and effective. The WTF – and that stands for Wrench That Fits – can open way more than a beer bottle, and it can also serve in a number of other capacities, including gear tie.
Oh yeah, and it’s a keychain, too. Let’s not forget that since that’s technically what it’s called. So from now on, you can have the right-sized tool hanging off your belt without the need for a clunky set of wrenches. As if that’s not enough reason to pick one of these up, it’s from the maker of the Bottle Grenade.
