Abstract
Abstract A disposable scalpel handle adaptable for use by either right handed or left handed surgeons is produced in a single press swaging operation, in which there is no leftover material or ''''flash'''' which has to be removed. Since the disposable scalpel handle produced is perfectly symmetrical about its central axis, a blade can be mounted to either side of the blade holding portion of the scalpel, thereby providing a scalpel adaptable for use by either right handed or left handed surgeons.
