Lock Thy Knife and Throw Away the Key

Wait a minute there is no key involved here in the Knife Locker. Apparently the knife itself is the key. It locks into position with a 270-degree counterclockwise turn and kick starts the UV sterilization process. Ready for the next use, bright and shiny! That sleek house will look good on any kitchen counter, what do you think?
