A method for producing a solid component which in succession includes deforming a metal bar by forging using two dies in order to obtain an intermediate component including two fins one on each side of a solid part capable of forming the base of the metal reinforcement, the two fins being at a divergent angle α; deforming the two fins of the intermediate component, altering the divergent angle α, so as to obtain the final shape of the turbomachine blade leading edge or trailing edge metal reinforcement.
