The first step is to cut chopsticks into sections according to a certain length. Step 2, break the cut chopsticks into bamboo strips with a certain width. The third step is to remove the knots from the chopsticks and flatten them. The width is also limited. Step 4, the smooth bamboo strips are processed into long bamboo filaments with the thickness of toothpicks. Step five, the bamboo shreds are cooked at high temperature, and then dried or dried. Step 6, cut the bamboo filaments into multiples of the length of the toothpick. Step 7, cut the bamboo into more than one foot sections of toothpick sticks. Step 8, polish the toothpick stick smoothly. Step 9, sharpen one or both ends of the toothpick stick.
