This was my conch tenderizer in my club in Jamaica from mid 70's - 80's. Never gave any thought as to what it's original use was. Never had a handle on it but would guess it would be 30-35 cm. A handle with a 1 1/2 kg head on the end seems a bit much for tenderizing steaks. Works great on conch with no handle.
Any ideas as to original use?
