The Knuckle Sandwich is a food item developed in the early 1920’s by murderer and restaurateur, Sal Bentworth, reportedly as a result of an accident in which a large amount of knuckles, which Bentworth was prone to store above his counter-top, fell onto a sandwich he was preparing before embarking on a routine afternoon killing. The Knuckle Sandwich is primarily served in North America, but variations are served worldwide, using local and regional knuckle. Recently the quality of knuckle sandwiches have fallen, using far less knuckles than is recommended for daily intake.
