Forget your tool? Not if you have your keys. 4 in 1 is better than bringing none. One tool unlocks your car, the other unlocks your beverage.
If you like leather and metal and you ride a bike, then you want this keychain to channel your inner Viking. Lashed to your car keys, use the 5mm hex wrench to remove a thru axle (common on many modern bikes) and stuff a bike inside your auto. The 4mm hex wrench will adjust most cockpit components like shifters, brakes, stem, seatpost, and more. Reward yourself with a beverage using the alloy bottle opener.
