Abstract
A method to produce a composite blank for a knife blade and, to produce knife blades from it. Each half of a pair of substrate halves has a groove filled with a powdered titanium carbide based metal matrix composite (Fe/TiC). It is placed in a metal container which is sealed, evacuated, and subjected to hot isostatic pressing (HIP) to cause the powder to sinter and bond to the halves. The container is cooled and removed from the contents. The metal halves are separated, and sliced to form the blanks, and the blanks are sharpened to form the knife blades.
