Abstract

A hand-held power tool includes a tool housing on which an ergonomic handle is formed for a user's hand, including the user's thumb, index finger, middle finger, ring finger, and small finger. The handle includes a first region for the index finger and the thumb, a second region for the middle finger, a third region for the ring finger, and a fourth region for the small finger. The second region has an approximately oval cross section with a first main axis and a first secondary axis. The third region has an approximately oval cross section with a second main axis and a second secondary axis. The fourth region has an approximately oval cross section with a third main axis and a third secondary axis. The first main axis is longer than the second main axis, and the first secondary axis is shorter than the second and third secondary axes.
