A hand operable wrench is described which comprises a wrench head at one end thereof, and a substantially metallic lever formed as a handle extending in a longitudinal direction from the wrench head. The wrench head has an imaginary axis of wrench rotation, and the handle is formed substantially nontwisted comprising a first handle portion, a second handle portion and a third handle portion. The first handle portion connects to the wrench head, and the second handle portion is longitudinally positioned between the first and third handle portions. The first and third handle portions each have a cross-sectional shape when viewed in a cross-sectional plane substantially perpendicular to the longitudinal direction. The cross-sectional shape of the first handle portion is elongated in a direction substantially perpendicular to the axis of wrench rotation of the wrench head, and, the cross-sectional shape of the third handle portion is elongated in a direction substantially parallel to the axis of wrench rotation of the wrench head.
