Claims16
A subassembly for a shaving razor comprising:
- a first elongated metal blade having a vertical base portion and an angular upper portion extending at an obtuse angle relative to the vertical base portion, a first cutting member mounted to the angular upper portion, the first cutting member having a first cutting edge defining a first shaving surface, the vertical base portion of the first elongated metal blade having a first and second longitudinal end;
- a second elongated metal blade having a second vertical base portion and a second angular upper portion extending at an obtuse angle relative to the second vertical base portion, a second cutting member mounted to the second angular upper portion, the second cutting member having a second cutting edge defining a second shaving surface, the vertical base portion of the second elongated metal blade having a first and second longitudinal end;
- a first metal plate and a second metal plate, said first longitudinal ends being connected by a first set of weld connections to said first metal plate, and said second longitudinal ends being connected by a second set of weld connections to said second metal plate;
- wherein said blades are secured only at said first and second longitudinal ends of the vertical base portions.
