Skalpeller

Skalpeller, commonly spelled scalpel, is a small, extremely sharp knife designed for precise incisions. It is a standard instrument in surgery, anatomy, and laboratory dissection, and is also used in some crafts. A scalpel typically consists of a handle and a replaceable blade; blades may be disposable or the handle may accept interchangeable blades.

Blades come in several standard shapes and sizes, most commonly designated No. 10, 11, 12, and 15. No. 10 is used for general incisions, No. 11 for pointed stab incisions, No. 12 for curved or hook-like incisions, and No. 15 for precision work. The blade geometry affects cutting dynamics and visibility in the working area.

Materials and design: blades are usually made from corrosion-resistant stainless steel or high-carbon steel. Handles may be stainless steel or plastic. Some systems use a disposable, pre-sterilized blade with a reusable handle; others are entirely disposable scalpel sets. In addition to traditional handles, safety scalpels with retractable blades reduce the risk of accidental injury.

Sterilization and safety: scalpels are sterile when packaged; blades are typically single-use in professional settings. Used blades are disposed of in approved sharps containers. Personnel handling scalpels should follow local protocols to prevent injury and contamination, including wearing gloves and using blade guards when appropriate.

History and usage: the scalpel lineage includes ancient blade instruments, but modern scalpels with interchangeable blades emerged in the late 19th and 20th centuries with advances in stainless steel and standardized blade shapes. Today they are essential tools in medicine, veterinary practice, and laboratory work, with variants tailored to surgical, dissection, and craft applications.
