The TUKK (Titanium Utility Knife Keychain) is a compact and highly portable tool that resembles a flash drive. By pushing the slider on the top forward, you can reveal a non-locking 1/2" razor blade. The blade can be easily retracted and stays closed with the help of an internal magnet. Please note that you must be at least 18 years old to purchase this item and it should not be stored in your pocket.
