The Avanti® Oyster Knife breaks open oysters with ease. This style of oyster knife is popular amongst restaurant chefs. It features a short thin stainless steel blade that easily slides between the shells, creating very little damage and limiting the amount of grit that gets into the oyster. The black handle has a flared guard that protects fingers and thumb from nasty oyster cuts. Easy-to-use, insert the tip of the blade into the hinge. Point it downwards in the cup of the oyster. Use a twisting motion to separate the top and bottom shells. You should feel the hinge pop when you twist the knife.
