We never leave home without some form of bottle opener on us, and the reason is simple: regret runs deep when you find yourself face to face with a gleaming bottle of import, its contents confined by a tiny steel prison. Ensure this doesn’t happen to you with a Keyshark, the lightest keychain opener available, and by a long shot – it weighs a ridiculous 1.07 grams (0.038 oz), made possible thanks to stress analyses and an aluminium body. Pop it on your keychain and forget it, but rest assured it’s got you covered when you need it most.
