A manual method of making a surgical incision in free tissue including moving a freely rotatable circular scalpel blade across an area of the free tissue at a desired incision depth without pressing the tissue to a mechanical backing member wherein the circular scalpel blade is rotated solely by friction between the blade and the tissue in which the incision is required. The scalpel blade may be pushed or pulled across the area of free tissue, preferably at a speed of between four and seven centimeters per second.
