FIG. 3 shows how to use the chopsticks 1 when the middle finger 6 of the five fingers 4 to 8 of the user's right hand cannot be used because it does not move or is cut off halfway. The one rod-shaped main body 2A is gripped by the thumb 4 and the index finger 5, the back side of the fingertip 5a of the index finger 5 is engaged with the finger engaging recess 3 of the rod-shaped main body 2A, and the other rod-shaped main body 2B Is sandwiched between the ring finger 7 and the little finger 8, and the back side of the fingertip 7a of the ring finger 7 is engaged with the finger engaging recess 3 of the rod-shaped main body 2B. Thus, one bar-shaped main body 2A is opened and closed by the index finger 5 and the middle finger 6 with respect to the other rod-shaped main body 2B, so that an object is pinched.

In this case, gripping one rod-shaped main body 2A with the thumb 4 and the index finger 5 and engaging the fingertip 5a of the index finger 5 with the finger-engaging recess 3 of the one rod-shaped main body 2A is performed by using FIG. This method is the same as that described above, but the other finger-like finger 7 and little finger 8 that are usually very difficult to grasp sandwich the other rod-shaped main body 2B, and the fingertip 7a of the ring finger 7 is engaged with the finger-engaging recess 3 of the rod-shaped main body 2B. Therefore, the ring-shaped finger 7 and the little finger 8 hold the rod-shaped main body 2B securely, that is, grip. Therefore, even if the middle finger 6 cannot be used, the chopsticks 1 can be fully used.

FIG. 4 shows how to use the chopsticks 1 when the right finger 5 of the user cannot be used because the index finger 5 does not move or is cut off in the middle, for example. Then, one rod-shaped main body 2A is gripped by the thumb 4 and the middle finger 6, the back side of the fingertip 4a of the thumb 4 is engaged with the finger engaging recess 3 of the rod-shaped main body 2A, and the other rod-shaped main body 2B is ring fingered. The rear surface of the fingertip 7a of the ring finger 7 is engaged with the concave portion 3 for finger engagement of the rod-shaped main body 2B, sandwiched between the finger 7 and the little finger 8. Then, one rod-shaped main body 2A is opened and closed with the thumb 4 and the middle finger 6 with respect to the other rod-shaped main body 2B, so that an object is pinched.

In this case, the thumb 4 and the middle finger 6, which are usually very difficult to grasp, grip one of the rod-shaped main bodies 2 A and engage the fingertips 4 a of the thumb 4 with the finger engaging recesses 3. 6 makes it possible to securely grip the rod-shaped main body 2A, and similarly, the other rod-shaped main body 2B is sandwiched between the ring finger 7 and the little finger 8 which are normally difficult to grip, and the fingertip 7a of the ring finger 7 is inserted into the finger engaging recess of the rod-shaped main body 2B. 3, the rod-shaped main body 2 </ b> B can be reliably grasped by the ring finger 7 and the little finger 8. Therefore, even if the index finger 5 cannot be used, the chopsticks 1 can be fully used.

Although illustration is omitted, for example, when the ring finger 7 cannot be used, one of the rod-shaped main bodies 2A is gripped by the thumb 4 and the index finger 5, and the back side of the fingertip 5a of the index finger 5 is the finger of the rod-shaped main body 2A. The other rod-shaped main body 2B is sandwiched between the middle finger 6 and the little finger 8, and the back surface of the fingertip 7a of the ring finger 7 is engaged with the finger-engaging concave portion 3 of the rod-shaped main body 2B. Good to do.

Although various examples of use have been described above, the finger engagement recesses 3 of the rod-shaped main bodies 2A and 2B are provided with the thumb 4, the index finger 5, the middle finger 6, the ring finger 7 and the little finger 8 according to the use situation.
