主权项

1. A manufactured blade for a cutting tool comprising:
a first elongated portion made of a first material; and a second elongated portion made of the first material and a second material, the second material being harder than the first material and deposited on the first material, the second elongated portion forming the tip of the blade, wherein the first elongated portion defines a first cutting edge having a first angle and the second elongated portion defines a second cutting edge having a second angle, the first angle being smaller than the second angle, and wherein a transition from the first angle to the second angle occurs in a region of the blade made of the first material that has been re-hardened during deposition of the second material on the first material.
