This is the finest nut cracker for removing shells from all kinds of nuts, including Pecans, Brazil Nuts, Walnuts, Almonds, and Filberts. (Not recommended for Black Walnuts or Macadamia Nuts). The handles are made of the finest cast aluminum. Plastic sleeves are fitted on the aluminum handles for comfort. 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 sheller is so easy to use. Just clip the ends and sides of the nut and perfect halves are produced.
