DETACHABLE SCALPEL BLADE [PDF]
JAMA: The Journal of the American Medical Association, 1913 In attempting to use safety-razor blades in surgical work I hfound a stock razor bladazorth ade with a straight cutting edge is not practical. Such a blade if held in the usual position will have only the distal corner in contact with the flesh and will tear rather than cut, especially if used in theideeper parts of a wound.
