An SFW (Special Effects) pro sword from the series "Spartacus Blood and Sand". This sword is a "Push Rod" sword used for battle scenes where the actor plunges his sword into his victim. The filming starts with a full prop sword usually made of resin or rubber, then as the actor is about to inflict the wound, the camera stops and this sword is substituted with the padded end against the victim. The cameras roll and the actor thrusts the sword forward,after releasing the lock on the handle, the silver aluminium shaft retracts through the handle behind his arm and movie blood sprays from the 2 tubes at the end of the shaft.
The blade is added in digitally post processing.
