Ok, I am up for this just to know. I found this in the kitchen drawer after divorcing my ex wife. The large part is about 2in in diameter and the blades are tapered (not sharp) for turning both directions. I have tried internet searches and can not find another one. WhatView attachment 201585 cha think? I certainly do not mind if you get help from your wives, girlfriends, mothers, or daughters. I have not thrown it away yet, but been close a few times.
Probably a good thing she's an ex!
