The Watson Skin Graft Knife (12 1/2") is a specialized surgical instrument used primarily in plastic and reconstructive surgery for harvesting skin grafts. The 12 1/2" length provides the surgeon with an extended reach, allowing for precise and controlled skin graft harvesting from donor areas. The knife typically features a sharp, fine blade designed to cut thin layers of skin without damaging underlying tissue, ensuring the graft is of optimal quality for transplantation.
