... But anyone who has ever screwed with it, will need to use anything else. Have such a short screwdriver loaned get (small screw, was not loszubekommen, am always slipped with my screwdriver without transmitting torque). So a colleague and told him "I need something smaller." Get the Wiha, think, Oh great, my Dreher is roughly the same size. Habs still tried and could not believe it. The previously unresolvable screw simply unscrewed. Have thus still worked done - as different as day and night. Unbelievable, 'only screwdriver'. Yet at the same hour ordered a set of these things and I am always glad when I've got something to screw and can use these things. Great. Very great!
