A single use self-contained surgical knife provides twist stability and lateral support for the knife blade. Turning a knurled ring member within th e containment casing retracts the knife blade into the containment casing. Retraction of the blade is permanent; once retracted, subsequent usage of th e knife blade is prevented. A substantial safety margin is provided, in that injuries occasioned by the retraction process are virtually eliminated. The knife blade remains forever in the retracted condition, preventing spread of blood borne infections such as AIDS, Hepatitis and the like, that might otherwise result from subsequent usage of the knife blade.
