 A cutting tool consists of at least one cutting blade. The cutting blade is composed of a blade body, a shank, and a blade edge. The blade body and shank are composed of a titanium alloy having a hardness of less than 20RC. The blade edge is composed of a titanium alloy having a hardness of greater than 35RC. The blade body and blade edge are connected by an intermediate border layer, formed during molding and sintering steps in the production of the cutting blade. The blade body, shank, and blade edge are all formed as a single body. The method for forming the cutting blade comprises the steps of molding different titanium alloy powders at a pressure between 2 and 15 tons/cm.sup.2, followed by sintering at 1100.degree. C. to 1300.degree. C.
