Break papers with one inch punch. One Inch Punch Brutal SPEED and POWER
There are two types of one inch punch, one is when the fist is only one inch away from the force-receiving point, and the other is when the fist is exerting force and is only one-inch away from the force-receiving point.
The child in the video used the second type of one inch punch. After punching straight, he used force to break the paper within an inch.
