Description(English)	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.
Description(Native)	손잡이를 돌려가며 깎던 연필깎이는 어느 제품이든 항상 같은 구조로 이루어져 왔으며 사용되어져 왔다. '밀당 연필깎이'는 밀고 당기며 사용하는 독창적인 방식을 가진 연필깎이 디자인이다. 연필을 깎을 때 8~9바퀴의 기어 회전을 필요로 하는 기존 연필깎이와는 다르게 '밀당'은 한번 지나갈 때, 3~4바퀴의 기어회전 효과를 낼 수 있어, 사용 시 동작 횟수를 절감하는 장점이 있다. 내부 레일을 따라 회전하는 기어에 연필깎이 칼날이 장착되어 있으며, 칼날을 양면으로 배치하여 밀거나 당길 때 모두 연필이 깎이는 구조로 제작되었다.
