Abstract
Numerous sharp knives are the essential tools for all surgery. Straight double-edged pointed knives, double-edged curved blunt-end knives, and button-end straight or curved knives are commonly used. They must be sharp at all times. Sharp blades reduce operative bleeding. They reduce trauma to the soft tissues. They decrease postoperative edema and ecchymosis. Goldman, in 1952, presented a "throw-away" button-end knife. I have developed a series of blades for use chiefly in rhinoplasty. These are necessary to separate the skin over the nasal pyramid in preparation for reconstruction of the bony and nasal components. They are particularly useful in secondary or revision work. These blades fit the standard Beaver handle. The blades lock in the handle easily and can be readily removed for replacement by the other blades. The handles are made of stainless steel. The blades are made of Swedish steel and are 5 mm. wide and 4 cm. long.
