Abstract

The invention relates to an axe comprising a blade (1) provided with a cutting edge (2) at one end, and a handle (3). The centre of gravity (C) of the axe is located at a distance from the cutting edge (2) of the blade and lies in a centre-of-gravity plane (A) of the axe located at a distance from a blade plane (B) of the axe parallel with both the centre-of-gravity plane and a normal working motion plane (E) of the axe. The cutting edge (2) of the blade and the centre of gravity (C) of the axe are arranged to cooperate when the blade (1) hits wood (4) and the cutting edge (2) of the blade partly penetrates into the wood (4) such that at least some of the impact force of the blade (1) is converted into a rotational motion. On the side of the blade plane (B) of the axe on which the centre of gravity (C) of the axe lies, the axe is equipped with first stop elements (6) arranged to hit the wood (4) during the rotational motion of the blade (1).
