PROBLEM TO BE SOLVED: To solve the problem that chopsticks are easily slipped to a certain degree when a user holds the chopsticks in a room with dry air in winter and the chopsticks are easily slipped when the user is not in a good physical condition or is aged with a weak grip. SOLUTION: Some chopsticks have several circular grooves along the circumference of the chopsticks in order to allow the user to easily hold food between them. In the same way, the chopsticks includes about 10 lines at an interval of 1cm, having a depth being a little larger than that of the grooves at the tip end of each chopstick, and arranged in a part to be held by hand. The lines are positioned from around the center of the chopsticks to the top end. COPYRIGHT: (C)2005,JPO&NCIPI
