A skin grafting knife, also known as a dermatome, is a specialized surgical instrument with a finely honed blade used to harvest thin, precise layers of skin from a donor site for skin grafts. It features an ergonomic handle for control and, in some models, an adjustable roller to set the thickness of the harvested skin. These knives are made from durable, corrosion-resistant medical-grade stainless steel, designed for precision and efficiency in reconstructive, plastic, and trauma surgeries to cover areas of skin loss from burns or wounds.
