A combination of surgical blade holder and cooperating blade is provided, which allows simple insertion of a blade having a specific configuration of opening in the tang for receiving a specific boss configuration on the handle, and closure to a locked position of the blade, upon insertion. The two parts of the handle pivot relative to one another in the same longitudinal plane around a pivot positioned adjacent the blade portion. This allows a relatively long handle portion for gripping the device for ejecting the blade, using the thumb or finger of the same hand for opening the holder. The gripping portion of the handle has adjacent to the blade portion thereof a boss which conforms to the opening in the blade tang. The boss includes a cleat with an overhang which serves to receive the opposed mating surface on the opposite half of the handle. The cooperating surfaces on the blade and handle provide three dimensional gripping of the blade closure which causes the movable portion of the handle to cover the boss and the blade tang. The mating surfaces on the handle include opposed surfaces for gripping the blade rib. When opening, the user pushes the movable portion of the handle open while holding the blade and boss of the fixed handle portion facing downward so that the blade falls out of the device, without any touching or movement of any kind, into a collector.
