Abstract
A method of manufacture of a knife blade comprises: (a) abutting a cutting body conformably to a spine body at a joint edge of the cutting body, the cutting body comprising a cutting material, and the spine body comprising a spine material distinct from the cutting material; and (b) directing laser radiation onto the joint edge from opposite sides of the cutting and spine bodies concurrently, thereby forming a laser-welded joint joining the cutting and spine bodies along the joint edge. In an example, the laser-welded joint comprises no material other than the cutting material and the spine material.
