Specifications of the scalpel Components: consists of handle (numbers 3, 4, 7, 9) and blade (numbers 11, 12, 15, 20, 22, 23). Materials: mostly from carbon steel or high-quality stainless steel. Types: Surgical (sterile): for medical and cosmetic use (removal of dead skin, acne). Craft: for cutting paper, cardboard, fabrics, and leather (like paper scalpel). Numbers: specify the shape and size of the blade; number 11 for fine incisions, larger ones (like 22, 23) for bigger incisions. Usage method Prepare the scalpel (surgical): ensure the blade is sterile, attach it carefully to the handle (or use a separate handle and blade if needed). Prepare the scalpel (craft): slide the blade with the side button to the desired length and secure it. Cutting: hold the scalpel comfortably and cut away from the body and user, using appropriate cutting techniques (for tissues or materials). After use: reattach the blade (craft) or detach it (surgical). Warnings and precautions Safety: very sharp; handle with caution to avoid cuts. Children: keep out of reach of children. Sterilization (for surgical scalpel): must be sterilized before and after use. Disposal: dispose of used blades in designated sharps containers. Cover: use the protective cover to keep the blade safe and prevent accidents.
