OnceAYearKnife (Randomly Generated Product Design)

Using Protobot.org, I had a product generated.

Premise of this product:
Once a year, Auntie Brenda comes over for Christmas, bringing her shoe-boot leather beef joint. You know she can't cook, but you don't want to disappoint her. But no regular knife can get through that.

Introducing the OnceAYearKnife, the knife that is always sharp because you CAN'T use it any other day than the date you set. Once the day arrives, the knife unlocks and is usable.
