It would be easy enough to make such a screwdriver. Start with a round shank screwdriver with a tip big enough to solidly address the screw slot. Bust the handle off of it, turn (or have someone turn) a metal bushing (can be brass, aluminum, or any old thing- heck even wood would probably be ok) to fit snugly onto the screwdriver shank with an out side diameter close to the hole diameter. Fabricate a new handle, or just clamp onto it with a pair of vice grips.
