| Abstract: |
A device for assisting in the use of chopsticks and a method of making same characterized by a band spring of single-piece, molded or formed construction, free of separate and joined members, to connect a pair of chopsticks at an adjustable distance from each other and enable their manipulation in a manner substantially identical and faithful to the proper holding and wielding of a pair of individual and unjoined chopsticks. The spring's structure consists of a curved and bent band spring extending between and terminating in two sleeves with adjustable apertures through which the chopsticks are passed. Forward disposition of one sleeve relative to the other sleeve causes one chopstick to have an axial component of movement when pressed toward the other chopstick. The sleeves are self-securing in their attachment to the chopsticks and can accommodate chopsticks of varying size. The distal space between the chopsticks can be altered to adjust the spring for holding by hands of differing size.
