| Abstract: |
A pair of coupled chopsticks for grasping food is disclosed. The coupling intermediate each of the chopsticks is formed by a pair of coil springs. Each of the coil springs includes arms extending therefrom, each arm of each coil spring being attached to one of the chopsticks. A clamp secures the two coil springs to each other in axial alignment. The axis of the pair of coil springs represent the point about which the chopsticks pivot. The arms of the coil springs maintain the chopsticks aligned within the same plane. Thereby, one end of the pair of chopsticks can be squeezed together to grasp food without having the pair of chopsticks become skewed.
