I still think its designed to crush/blend/mash...........
It was a serious idea.
I remember seeing a latch or handle on a walk in freezer one time and the handle was inserted into three slots.
It was pushed into the slots and raised or lowered opening the door.
Then the clerk would take the key away with them for safe keeping.
I remember this, but have no idea as to the origin of these memories.
But something tells me that tool inserts into something to do a mechanical operation? Just taking a stab.
