  • Training chopsticks
    Patent number: 8562054
    Abstract: Chopsticks are provided including a first chopstick and a second chopstick which have been modified to be readily coupled together. Bores are formed in each of the chopsticks. A pin is supplied which passes through each of the bores. The pin has a friction fit within the bores such that the chopsticks are held together. The pin resiliently flexes when distal ends of the chopsticks are brought together, so that the pin provides a return force to the chopsticks. The bores and pin preferably have a non-circular cross-section so that the chopsticks are held within a common plane. The pin can have at least one tip that is pointed so that the pin can double as a toothpick.
