A utensil to open a shell of a shellfish, including a first end comprising a shell breaking tool, the shell breaking tool including a first member extending longitudinally away from the handle such that a portion of an end of the first member is inclined into a wedge, a second member disposed adjacent to the first member and extending longitudinally away from the handle, such that a gap is defined between at least a portion of the first member and the second member, and such that the first member is longer than the second member, a second end opposite the first end, and a handle to connect the first end to the second end.

A utensil to open a shell of a shellfish, including a first end including a shell breaking tool, a second end including a fork, and a handle to connect the first end to the second end, such that at least a portion of a bottom surface of the handle includes a sharpened edge.

An oyster clamp comprising a base element having an indentation for receiving an oyster to be opened. A lip coupled to the base element hangs over and impinges upon an edge of a work surface on which the oyster clamp is placed, and a slide inhibitor is arranged to prevent the base element from sliding on the work surface. A backstop is affixed to the base element to prevent the oyster from exiting the back of the oyster clamp when in use. An oyster clamping element is operatively coupled to a handle and to the base element, such that operating the handle causes the clamping element to push the oyster down against the base element.
