Prototype of tools for learning the force balances of chopsticks has been made. When chopsticks hold something, two tips of chopsticks push by same strength on each other. However, it is difficult to find out the scientific report which discusses force balances of chopsticks, although there are some research papers discussing chopsticks. Many of them discussed shape of hand, and do not explain the method of chopsticks training clearly. Prototype proposed here is made of disposable round chopsticks, vinyl tape, and thin plastic sheet. When the prototype chopsticks for training are grasped by traditional type of gasping chopsticks, thumb bends thin plastic sheets. Therefore, the shapes of plastic sheets suggests whether or not thumb holds chopsticks Accuracy of the tips of the chopsticks is visualized by pinching PET Bottle chap. Validity of the prototype of chopsticks for chopsticks-training and the method was suggested by chopsticks use by the non-dominant hand.
