Method for producing cutting tools comprises steps of pressing blade metal blank against base metal blank while continuously rotating one of blanks relative to other for purpose of developing frictional heat. Relative rotation of blade and base metal blanks is terminated after sufficient heat is developed but pressing force is maintained. Blade and base metals are joined together to form rough forging of cutting tool. Rough forging is forged to draw it along juncture of blade and base metals. Portions of blade and base metals are cut away to form cutting tool.
