A device for breaking the shells of nuts, such as walnuts, pecan nuts, cashew nuts, almonds, macadamia nuts, hazelnuts, where such device includes a sleeve with a through hole along an axis, elastic gripping means which can exert a force in a preferential direction coupled to the end of the sleeve in a manner such that the preferential direction is substantially coincident with the axis of a base, and a means for rotatably mounting the sleeve with respect to the base about an axis which is perpendicular to the axis, in a manner such that the sleeve is capable of taking up a first position in which the plane of the second end of the sleeve rests substantially on the face of the base and a second position in which the plane of the end of the sleeve makes a non-zero angle with the plane of the face of the base.

A crab shell cutter is provided which has first and second handles and first and second jaws which pivot relative to one another. The jaws include a tapered jaw line which comprises having a tapered surface from which a plurality of serrations extend. The serrations are pyramidal in shape. When engaging a crab shell, the plurality of serrations form linear perforations in the shell but inhibit damage of the underlying crab meat.

A nut cracker includes a main member with a first handle portion extending therefrom, a gear cutter member including a gear cutter, a clamping member including a clamping bar connected to the first handle portion to cooperatively form a handle, and a stopping switch member connected to the main member. The clamping bar can drive the gear cutter move when the handle can move back and forth between a first state and a second state under an external force. In the first state, a distance between the first handle portion and the clamping bar is minimum, with the clamping bar meshed with the gear cutter. In the second state, a distance between the first handle portion and the clamping bar is maximum, with the clamping bar meshed with the stopping switch member to prevent the gear cutter from backing off to avoid crushing flesh of nuts due to excessive force.
