UMD: Surgical knives designed for cutting fibrous connective tissue (i.e., cartilage). These knives consist of manual, sturdy, handheld instruments usually with a wide straight tubular handle and a long, flat, stiff cutting blade at the distal tip. These knives frequently have concave U-shaped guards. The handle may be finished in a perpendicular plate at the proximal end to facilitate hitting with a mallet. Cartilage knives are mainly used in orthopedic procedures.
