Claim:
An ergonomic handle for a power tool having a power source, a housing containing a source of motion, and a tool holder coupled the housing and defining a tool holder axis and a forward direction toward a working end of the tool and rearward direction away from the working end of the tool, the handle comprising: a handle portion having a proximal end coupled to the housing and a distal end coupleable to the power source, and defining, from the proximal end to the distal end, a first region, a second region, a third region, and a fourth region, and defining a handle axis that is generally transverse to the tool holder axis; the first region adjacent to and distal of the proximal end, the first region including a switch for actuating the source of motion and adapted to receive a user's thumb and forefinger when the forefinger is actuating the switch; the second region adjacent to and distal of the first region, and adapted to receive the user's middle finger; the third region adjacent to and distal of the second region, and adapted to receive the user's ring finger; and the fourth region adjacent to and distal of the third region, and adapted to receive the user's pinky finger, wherein each of the second region, the third region, and the fourth region includes a generally oval cross section having a major axis and a minor axis, where the cross section having the longest major axis is positioned in the third region, the cross section having the shortest major axis is positioned in the fourth region, the cross section having the shortest minor axis is positioned in the second region, and the cross section having the longest minor axis is positioned in the fourth region.
