ABSTRACT:
A nutcracking apparatus having a base and a member attached at the bottom thereof to the front and top portions of the base and extending upwardly therefrom. A first nut contacting blade is attached to the one side of the member. An elongated plunger has a second nut contacting blade attached to one end thereof and guide structure is provided for reciprocally mounting the plunger to the base to cause the plunger to stay in the same path during reciprocation between a first position and a second position for cracking the nut. A handle is pivotally attached at one end thereof to the other end of the plunger along the first axis and a cantilever structure is rigidly attached at one end thereof to one end of the handle and extends in one direction away from the first axis. A link member is pivotally attached at one end thereof along a second axis to the other end of the cantilever and at the other end thereof to a top portion of the guide structure, whereby pivotal movement of the handle from a first position thereof to a second position thereof causes a corresponding movement of the plunger from the first to the second position thereof, thereby opening a nut which has been placed between the blades.
