This precision compass is designed to cut holes in leather or paper crafts and includes five spare blades stored in a built-in compartment, along with a measuring guide. Unlike standard compasses, it features a precision measuring scale and uses a soft rubber center anchor instead of a needle, preventing unwanted holes in the center of your cut. The design ensures even pressure distribution, minimizing the risk of jagged, warped, or uneven circles. Ideal for cutting precise circles in leather, paper, cardboard, rubber, and similar materials, this compass cutter holds material securely with a rubber pivot point, eliminating the need for a center punch. Perfect for various craft applications. The compass features a sharp cutting blade that easily cuts through leather and paper. Includes six cutting blades. Compatible with BDC-400P replacement blade pack. Cutting diameter range: 1.8 cm to 17.8 cm (0.7 inches to 7 inches).
