At Jean's Restaurant Supply we carry a wide selection of specialty knives for your restaurant's kitchen supply. An oyster knife has a short, thick blade that is used to pry open oysters and separate their meat from the shell. Some models have a shield built into the handle that prevents the knife and hand from slipping and going too far into the shell. A clam knife is essentially an oyster knife, and is used to pry open clams. Fillet knives are used to cut fish parallel to the spine, eliminating the bones and making the fish safer to eat.
