Abstract
The invention proposes a handle for a screwdriver or a similar tool, which over a significant part of its length has a cross-section in the form of an approximately regular pentagon. The corner or angle sections are rounded with a radius of curvature, whose centre is in the longitudinal axis of the tool handle. The corner sections formed by the curved part of the cross-section have a different width over the handle length. The shape of the flattenings does not follow the shape of the handle contour.
