A blade for food processors is provided on at least one surface with a plurality of spaced cutting teeth, which are slantingly or perpendicularly projected from the surface of the blade. Each of the cutting teeth includes a substantially pyramidal projection and a substantially triangular shallow recess located in front of the pyramidal projection. When the blade is mounted in mixer, juicer, or other types of food processors, the cutting teeth cooperate with serrated edges of the blade to very quickly cut, grate, grind, and press fruit or food to produce highly fine granules and juice.
