Locking Finger Chopper

You show a clear plastic finger chopper with a hole for the finger and a hole at the bottom for a carrot or something similar. You show that anything placed either of the hole will be cut by the blade inside the finger chopper, yet when you place your finger inside the finger chopper, miraculously the blade passes right through the finger without hurting your finger.

Blade is not razor sharp but due the locking mechanism this product is NOT intended for children.
