Prepare materials: Vice/clamps, pencil, fine-toothed/bamboo saw, and sanding paper.
Measure and mark the desired length on the bamboo stick.
Secure the bamboo pole in place, preferably with the help of a vice or clamps.
Choose a fine-toothed saw or a bamboo-specific saw.
Cut slowly and steadily along the marked line. Apply even pressure to prevent splintering.
Sand the cut edge to remove splinters or roughness.
Dispose of bamboo offcuts with care, as they can be sharp and hazardous.
