  • Patent number: 4973095
    Abstract: Two parallel chopsticks are interconnected by a transversely extending spring member which extends directly across between the two chopsticks to form a perpendicular extension from one chopstick which directly interconnects with the other chopstick. An ornamental design may extend from opposite edges of the transverse interconnecting member in a direction extending parallel to the chopsticks. The spring member is designed to give the correct feel for use of chopsticks. The cross-section of the spring member can be modified to give this correct feel. An additional feature is a guide locking member which interconnects the two chopsticks approximately at their mid-points.
