1.The upper side is a broken chopstick. I used to think that the material was wood, but if you look closely, it looks like bamboo.

2.First, make a chuck attachment that grabs chopsticks. Drill a 7 mm in the round bar.

3.Make a slit with a saw.

4.Grasp the metal part of the broken chopsticks with a three-claw chuck.Then turn the bamboo part.

5.This part is brass. Diameter 4.2 mm * length 15 mm.

6.This is the material bamboo.

7.Mark the edge of the bamboo a 8mm circle and use a hatchet and knife to shave it into a about round bar.

8.Drilling 4.2 mm.

9.Glue the brass parts and bamboo with ”Cemedine Super X2”.

10.Turning to 7 mm.

11.Turning it into a taper.

12.From near the center to the tip, shave it in a square with a sander.

Finish with urethane "kigatame ace". The upper side is the repaired chopsticks.
