The mixture of materials consists of titanium powder or titanium alloy powder for a first material, titanium carbide for a second material, and silver powder for a third material. The proportion of the second material to the first material is 5-50 weight %, The proportion of the third material to the total amount of the first and second materials is 0.1-10 weight %. The hardness of the sintered body is preferably more than HRC 35.degree.. Cutlery produced from the sintered material has a remarkable antibiotic activity together with excellent sharpness and durability of the blade edge.
