The invention relates to a rotating blade having a sheath (10) that has a uniform assembly direction over the radial height of the sheath whether the blade has a straight or curved trajectory. This is achieved by the sheath formed around the leading edge (7), having a first inner surface (14), wherein a first tangential vector (18) projected tangentially to the first inner surface in a direction away from the head portion (20) in a longitudinal plain forms a first angle (16) with the rotational axis (2) that does not vary over the radial height (3) of the sheath while a second tangential vector (28) projected tangentially from any point of the second inner surface (24) of the sheath in a direction towards the head portion intersects the first tangential vector.
