Recently, while cleaning out my mother's kitchen, we came across this tool:
When closed, it is about 8 inches long (the box at the end is maybe 2 inches by 2 inches by an inch or so). The two sides come apart very easily. The tool is quite light-weight, and seems to be made of aluminum. Other than that, I have idea what it could be, and there seemed to be no identifying marks or branding.
Honestly, I would not be surprised to learn that it is not even a kitchen tool (my money is on Medieval torture device), but it came from one of the kitchen cabinets, so maybe it belongs there?
