1. A surgical scalpel, comprised of:

  • the scalpel including a body having a rear portion and a forward portion;

    a surgical cutting blade;

    a surgical cutting blade attachment projection for receiving the surgical cutting blade thereon, the cutting blade attachment projection being integrally formed on the forward portion of the body of the scalpel and extending forwardly therefrom, so that the cutting blade thereon extends forwardly therefrom;

    a cutting blade guard carried by the body of the scalpel for selective longitudinal sliding movement of the guard on the body between an extended position, wherein the guard extends over the cutting blade, thereby selectively covering the cutting blade and protecting the user thereof, and a retracted position, wherein the guard is rearward of the cutting blade, thereby selectively exposing the cutting blade and permitting the use thereof; and

    a resiliently-biased detent means formed between the body of the scalpel and the blade guard for removably securing the blade guard in the respective extended and retracted positions thereof wherein the resilient-biased means includes;

    the cutting blade guard having at least one pair of locking detents formed therein, one of the locking detents of said pair being formed in a forward portion of the cutting blade guard, and the other of the locking detents of said pair being formed in a rearward portion of the cutting blade guard; and

    a resiliently-biased means carried by the body of the scalpel for selectively mating with one of the respective locking detents of the pair of locking detents formed in the blade guard when the blade guard is disposed in the respective extended and retracted positions thereof, whereby the mating of the locking means with the one of the locking detents formed in the forward portion of the blade guard removably secures the blade guard in the respective retracted position thereof, and further whereby the mating of the locking means with the one of the locking detents formed in the rearward portion of the blade guard removably secures the blade guard in the respective extended position thereof.
