The Duke Pecan Nut Sheller nips nuts, especially pecans, from the sides of the nut, releasing it in perfect halves. Works great for Brazil nuts, almonds, walnuts, and hazelnuts. The handles are made of the finest cast aluminum. The shell deflector shield allows indoor nut shelling without making the mess that nut crackers create. Remove the shield and you have a great tool for lobster or crab legs. This Nut Sheller is so easy to use. Just clip the ends and sides of the nut and perfect halves are produced. Not recommended for Black Walnuts or Macadamias.
