Method for producing a metal reinforcement for protecting a leading edge of a compressor blade of composite, characterized in that the method involves the steps of: - creating a core (3) that has the shape of the internal cavity of the reinforcement, - creating an insert (7) made of an alloy of a hardness greater than that of the reinforcement, - shaping sheet metal by stamping with the creation, upstream of said core, of a cavity (6) between the metal sheets which cavity is able to accept said insert, - positioning said sheets around said core (3) with the insert (7) placed in said cavity (6) and securing the assembly together, - the creation of a vacuum and the closing of the assembly by welding, - consolidation by hot isostatic pressing, - cutting of the assembly to extract the core (3) and separate the reinforcement, - creating the external profile of the reinforcement by a final machining operation that reveals the material of the insert (7).
