I own several Spitfires, including my favorite, a S35VN with a bead blasted blade. I want to change the arrangement of the blade clip and saw that I need a very tiny Allen wrench to remove the inserts from the holes. Does anyone know where I can obtain one? It is smaller than the smallest wrench I own. if I know what size it is I can order one from someone online, but I don't want to by a complete set.
