The 1/2 Fomon Rasp 4 Sides DE Coarse is a surgical instrument commonly used in plastic and reconstructive procedures, particularly rhinoplasty. It features four working surfaces for versatile shaping and contouring, and a coarse texture ideal for aggressive removal of bone or cartilage. The 1/2 size refers to the width, making it suitable for mid-sized areas, while the DE (double-ended) design offers added flexibility during surgery.
