The smooth hard zones move through tha hand like wheels when repositioning the hand on the handle. The easy-to-grip soft zones provide optimal contact zones for the muscles of the hand to transfer a high amount of torque. The micro-rough surface "bites" into the screw head and ensures that the screwdriver is held securely in the screw. Reduction of cam-out effect and reduction of required contact pressure.
