Made circa 1980, has processed many hundreds of pounds of nuts and still going strong! This is the best and easiest-to-use nut cracker I have ever used. The box it came in is in sad shape, being repaired twice with duct tape, but the nut cracker is in very good shape and ready for another 50 years of service. Comes with instruction sheet.
You will find these on Ebay from $25 to $100 each.
