    Abstract: The present invention relates to a metal fibre (1), at least one side face (2, 3) of the metal fibre (1) being provided with recesses (12, 22; 13, 23). It is preferred that the recesses (12, 22; 13, 23) are positioned at a regular distance from each other, and that the at least one recess (12, 22; 13, 23) is recessed with respect to the side face (2, 3) of the metal fibre (1) over a distance which is less than 50%, preferably less than 30% of the width of the metal fibre (1). The metal fibre (1) may further be provided with a plurality of undulations (6) extending in length direction of the metal fibre (1). The invention also relates to a method for producing such a metal fibre.
