A method of producing a razor head including one or more blades, a plastic guard member and a plastic cap member, the plastic guard member having an internal surface and a peripheral wall defining an internal volume, the method comprising the steps of:
- a) securing the one or more blades fixedly to the plastic guard member separately and independently from the plastic cap member with a securing pin and forming a crimping head at one end of the pin to rivet the blades onto the plastic guard member, the one or more blades being disposed in the internal volume without projecting outside of the internal volume so that when mounted on the plastic guard member, the plastic cap member abuts against the peripheral wall of the plastic guard member, and
- b) mounting the plastic cap member and then laser welding the plastic cap member onto the peripheral wall of the plastic guard member with a laser beam, the step of securing the one or more blades fixedly to the plastic guard member being achieved before the step of mounting the plastic cap member.
