Patented machine designed to extract meat from the Atlantic blue crab. If used as directed, the Crabmaster is guaranteed to perform as advertised. Just place the crab in the machine, pull the lever and rake out the crabmeat. After you get familiar with the Crabmaster, you can get the meat out of about 3 dozen crabs in 15 to 20 minutes. With the Crabmaster, you get more meat and less shell per crab than when boiled or steamed and hand- picked.
