Abstract: 
The procedure consists of making the blade in two sections (10, 12), each of which is drawn, rolled, stamped and machined separately and then joined together The two sections are made from materials with different properties, eg a high alloy maraging steel for the tip and a carbon steel for the upper section, and the two are welded together The two sections can be given their thermal treatment prior to assembly, and given their finishing treatment after assembly The tip of the blade can be made with one or more breaking points ADVANTAGE - Greater safety with improved mechanical performance
