  • Method of making a screwdriver
    Patent number: 5461944
    Abstract: A screwdriver includes an enlarged blade and a straight bit with parallel opposing surfaces. The surfaces apply torque to a screw slot over an increased area and reduce the tendency of the bit to slip out of the slot as compared to conventional commercially available screwdrivers. The screwdrivers are preferably made of hardened high quality steel so that they will be strong enough to withstand a substantial amount of torque.
