This Wing Handle torx bit driver from Wiha Tools offers high torque transfer when working with small screws. It has a molded green wing handle with a top spinner grip nob. The bit is made from special chrome-vanadium-molybdenum tool steel that has been through hardened for the best possible wear resistance. This Wing Handle model comes in a T6 size.
These are now made in Poland. The quality is just so-so. The tip is quite soft and only suitable for light-duty work. If the screw has thread locker on it, then the tip will strip out before the screw head. That's right, the tool will fail before the screw. It's cheap and convenient, with a nice handle shape, but don't expect much.
