The Buddhist bead cutter is a specialized forming tool used for manually crafting prayer beads and bracelet round beads. Its core function is to efficiently and accurately turn standard round beads. A complete set typically includes multiple fixed-specification curved-edge round knives, each corresponding to a specific bead diameter. During use, materials such as wood or amber are secured and rotated, while the corresponding round knife is fed into the material for cutting, achieving a single-step forming process. This ensures complete uniformity in size and shape for beads within the same batch, significantly enhancing production efficiency and finished product precision. It simplifies the laborious process of traditional manual rounding, serving as a core tool for cultural relic DIY and precision woodworking.
