Abstract: A high inertia cylindrical mass element having one or more food chopping blades detachably affixed thereto is positioned within a transparent cylindrical tube containing food to be chopped. The tube containing the high inertia cylindrical mass element is dimensioned to permit the tube to be moved back-and forth much more than the mass element is moved therein due to the high inertia of the cylindrical mass upon the manually induced to-and-fro motion of the tube by the user that results in chopping of the food. In addition to creating the back-and forth movement of the tube, the user also twists the ends of the tube with her wrists while the tube is grasped which results in relative rotary displacement of the tube relative to the high inertia cylindrical mass carrying cutting blades that tends to chop the food more uniformly.
