I can help, but I need a bit more detail to identify it accurately. Can you describe it more? For example:
- Its size, shape, and material (metal, plastic, wood, etc.)
- Any moving parts or mechanisms
- Whether it has teeth, bristles, holes, or slots
- How it feels when you press or twist it
From your description, “com” could mean “comb” or something similar, but thrift store kitchen gadgets often have unusual or specialized uses.
If you can upload a photo, that would make identification much faster and more precise.
