Chopsticks and knives and forks are fundamental utensils used by Asian and Western-oriented people, respectively, in
serving food. Although ergonomics studies on the knife handle have been performed, chopsticks, used by at least 1.5
billion people daily, have seldom been examined by ergonomists. This lack of interest may be attributed to the fact that
Occidentals, who tend to give more emphasis on empirical research, do not use chopsticks. Nevertheless, from an
ergonomics perspective, chopsticks deserve a systematic study in lieu of the large number of users. This study involves 32
male and female university students who served as the control group. According to these results, the diameter of
chopsticks signiÞcantly inßuences Ôfood-pinchingÕ e¦ciency. Also, the smaller and larger diameters of chopsticks are
inferior to those of a medium diameter. In addition, chopsticks with 6 mm diameter are optimum for Ôfood-pinchingÕ
e¦ciency. Subjective preference ranking is also used to cross-validate the above performance measures, with these results
