Abstract
Ergonomic chopsticks come with low-profile protrusions that are strategically placed. These protrusions generate tactile feedback on particular surfaces of a user's fingers, without hindering normal movements of fingers and chopsticks. They guide beginners and lifelong users alike to adopt a proper chopstick grip, allowing users to extend chopstick tips wide apart over an angle of 40 degrees. They help users twirl chopsticks from the closed posture to the wide-open posture, and back, based on principles of the planetary gear train, while ensuring that fingers and chopsticks stay within the standard grip form. As a result, a user can wield ergonomic chopsticks to embrace large food items with ease, manipulate these large items with dexterity and finesse in the same way she can small items, and generate enough compression force to hold all items firmly between ergonomic chopsticks.
