Abstract: Chopsticks comprise a lower chopstick member (20), an upper chopstick (10) and a hinge mechanism. The hinge mechanism comprises a hinge arranged on the lower chopstick member (20) and a hinge hole (102) in the upper chopstick member (10). The hinge comprises a hinge head (130) which can be received into the hinge hole (102), and the hinge hole (102) is provided with a pivot (164) that can be received within the inner chamber (132) of the hinge head (130), so that the hinge can turn around the pivot (164). The upper chopstick member (10) is provided with a swell portion (104), in which the hinge hole (102) is located, and the swell portion (104) extends from the front surface of the upper chopstick member (10) and/or the back surface of the upper chop stick member (10), therefore, the whole strength of the chopsticks is increased.

Abstract: A pair of training chopsticks comprises an upper chopstick member and a lower chopstick member. A thumb ergonomic device is provided, which does not directly contact the lower chopstick member, but fixed at the upside of the front surface of the lower chopstick member through a fixing element. The thumb ergonomic device is shaped in a curve, the opening of which substantially directs to the head of chopsticks, so that when the chopsticks are held, the curve opening touches a region of the ulnar side of the thumb not touching the lower chopstick member, for maintaining the correct relative position between the thumb and the lower chopstick members.
