A scalpel is a small, sharp knife used mainly in surgeries and medical procedures. It allows surgeons to make precise cuts in the skin and other tissues, which is essential for performing operations safely and effectively. The blade is usually made of stainless steel, ensuring it stays sharp and can be sterilized to prevent infections. In addition to its use in medicine, scalpels are also used in fields like art and model-making. Artists and hobbyists use scalpels for detailed cutting and shaping of materials, showcasing the tool's versatility beyond the operating room.
