摘要： The present invention relates to a multilayer cutting blade (1) comprising a core (2) that has a cutting wire (3), two side flanks (5), and two intermediate connecting thicknesses (4), the side flanks (5) being made of a corrosion-resistant tough metal alloy, each intermediate connecting thickness (4) having a first face (8) for connecting to the core (2) and a second face (9) for connecting to one or the other of the side flanks (5), the first connecting face (8) and the second connecting face (9) being made of copper or a copper alloy. - According to the invention, the core (2) is made of martensitic stainless steel, and the thickness of the core (2) is greater than or equal to one third of the thickness of the cutting blade (1), and preferably greater than or equal to half the thickness of the cutting blade (1).
