A nutcracker is described herein which comprises: a frame; an anvil and hammer movably mounted to the frame; a wedge ramp in a fixed relationship to the frame and having a substantially planar surface; a sliding wedge having opposing, substantially planar surfaces of which one surface is in sliding and flush contact with the surface of the wedge ramp, and the other surface is in contact with the anvil; a striker movably mounted to the frame for striking the hammer; and an anvil and hammer control device for moving the sliding wedge along the wedge ramp while in contact with the anvil so as to move the anvil relative to the hammer from an open position, in which ends of the hammer are at a maximum distance from one another to allow a nut to be received therebetween, to a closed position in which such ends are closed securely upon the nut, whereupon the control device causes the striker to strike the hammer and move it toward the anvil a predetermined distance to thereby crack the nut.
