A gripping device with a plurality of rods, pivotably engaged to at least two plates. As the plates are rotated in opposite directions, the distance between rods is changed. One specific embodiment of the invention functions as a pecan cracker. A pecan placed within the perimeter of the rods, between the plates, will, upon sufficient rotation be grasped by the closing rods. Upon sufficient farther rotation, the pecan shell will crack. Control over the force applied is usually sufficient to properly crack the shell without breaking the meat of the pecan.
