ABSTRACT:
A base is provided including a centrally upwardly facing roughened surface portion and the base includes a raised mounting point horizontally spaced to one side of the roughened surface portion. An elongated lever has one end pivotally anchored to the mounting point for swinging movement of the free end of the lever in an upright plane containing the mounting point and the roughened surface portion. The other end of the lever defines a handle portion and an intermediate portion of the lever is disposed over the roughened surface portion and includes a depending downwardly tapered wedge member supported therefrom including a lower apex edge extending transversely of the lever. When the handle portion of the lever is generally horizontally disposed, the lower end of the wedge member is generally horizontally aligned with the mounting point and spaced generally (X) distance above the roughened surface portion and 2(X) from the mounting point with the effective vertical extent of the wedge member from the intermediate lever portion downwardly to the lower tip of the wedge member being generally 11/2(X). The transverse lower apex edge of the wedge and its spacing relative to the lever intermediate portion, the lever mounting point and the roughened surface portion of the base assists in the use of the lever and wedge member to open a clam or oyster with minimum effort and increased safety.
