An idea for the walnut crusher. It is designed from two identical parts and is connected together with the screw and nut. The material is a soft rubber, plastic or even wood. The conical inner shape is designed to hold the walnut from all sides. At the bottom and on the top there is a spherical shape that breaks the shell. The inner volume is smaller then the wallnut volume. It is necessary to insert the wallnut inside, close the other half, hold it by the handle and hit it on the table. The advantages of this device is that it does not totally crush the walnut and the shell does not falls around.
