| Abstract: |
This invention relates to extremely inexpensive coupled chopsticks comprising a pair of sticks mechanically coupled to one another by a curled wire spring that is secured to the chopsticks in a novel way. The coupling of two sticks by a novel wire spring of the present invention is compatible with the conventional disposable chopsticks comprising two sticks partially attached to one another at one extremity thereof which are to be split into two separate sticks at the time of use as well as with the traditional chopsticks comprising two separate sticks.
