An axe comprising a blade (3) provided with a cutting edge (6) at one end, and a handle (2), and in which the centre of gravity of the axe is located at a distance from the cutting edge (6) of the axe and lies in a centre-of-gravity plane (C) of the axe located at a distance from a blade plane (B) of the axe parallel with both the centre-of-gravity plane (C) and a normal working motion plane (W) of the axe, and in which the cutting edge (6) of the blade and the centre of gravity of the axe are arranged to cooperate when the blade (3) hits wood and the cutting edge (6) of the blade partly penetrates into the wood such that at least some of the impact force of the blade (3) is converted into a rotational motion and a motion of the blade (3) in a curvilinear trajectory, the blade (3) is attached to the handle (2) so that the handle (2) is uncircled by the blade (3). |
