Very expensive set of different screwdrivers. The Kraftform- zone is a bad joke, with larger hands of Dreher is so badly in his hand, that hardly force can be exerted. In addition, the surface is hard and smooth, so the few bearing surface of the hand slips off quickly. Have the set therefore sent back and ordered me out of Felo () the appropriate Allen-turners, who have a much more pleasant handle and also are better deals.
