You are bidding on a great vintage cast iron, Nutcracker.  It is 4 5/8 Inches long, has some surface wear. Research indicates it is an older European nut cracker. It is reversable to adjust for smaller and larger nuts.   Nice one to use or for your collection.  Please check out the other vintage items I have listed this week.   I will combine shipping when I can if you purchase more than one item.
