Any pencil sharpener used by rotating a handle was created in the same way. 'push & pull sharpener'is a unique pencil sharper design that makes use both pushing and pulling. Unlike existing pencil sharpeners that require 8-9 gear rotations of the wheel when sharpening a pencil, 'push & pull sharpener'allows gear rotations of 3-4 gear rotations of the wheel each time so that it has the advantage of reducing the number of movements when used. Pencil sharpener blades are attached to the rotating gear along the internal rail, and blades are placed on both sides so that the structure sharpens the pencil whenever it is pushed or pulled.
