This is a nice, clean antique wood handle screwdriver with the knife handle or "PERFECT HANDLE" design. It is not marked by the maker, but is marked "CAST STEEL" and also marked "3" on the opposite side. The "3" most likely refers to the 3" of steel round shaft to the point, excluding the handle section. The overall length is 7". The handle fit the hand nicely, an excellent feel in hand. The steel is clean, no rust, the tip is in good shape, about 1/4" wide at the tip. The handle sections are in very nice shape, solid, no cracks, not loose, well attached, smooth finish with a few minor dings and scratches.
