ABSTRACT:
A process for fabricating a knife handle incorporating a decorative embedment upon a background of a different color than the knife handle. The handle is formed with a cavity having bottom and side walls and bounded by a lip which is raised from the outer surface of the handle. An undercut is made in the sides of the cavity, after which a plastic sealing material is applied to the bottom and sides of the cavity, in liquid form. A second layer of liquid plastic containing a dye of the desired background color is then poured into the cavity and allowed to harden, and the embedment is placed thereon. The cavity is then filled in one or more steps by a transparent plastic material. After hardening and curing of the plastic, the outer edges and surface are ground and polished to the final appearance.
