Effortless handle: with a hex hole on the bottom of the handle, the twist performance is strengthened by the hex wrench. With aided-fastener, users can gather the forward and twist forces to prevent the blade and screw from slipping in limited spaces. Torsion-van spring (TVS) handle: six hard slices (TVS) of PP are embedded in inner layer and are covered by soft TPR (thermoplastic rubber) on the outside. The users can twist and push the screwdriver at the same time, so TVS prevents the sole of the hands caused by long-time operation. Cross-section blade: innovative cross-section blade design can save the usage of steel and strengthen the break resistance.
