Abstract
A screwdriver comprises at least one housing and a rotatably driven screw-tightening tool projecting beyond said housing. For improving the screwdriver in such a way that, even under poor illumination conditions, it can be used safely and accurately without any additional expenditure of work on the part of the user, an illumination means is arranged at least partially on the housing especially for illumination in the direction of the location of use of the screw-tightening tool.
