1. A metal-cutting saw blade, comprising: a cutting edge including a plurality of teeth thereon, wherein the teeth each include a tip, a clearance surface located on one side of the tip, a rake face located on an opposite side of the tip relative to the clearance surface, a gullet, a flat or linear projection formed between the rake face and the gullet and projecting outwardly relative to the rake face and adapted to create curled metal chips and move the chips away from the rake face toward an opposite side of the gullet relative to the rake face, a junction radius formed between the projection and the rake face, and a flat gullet entry surface formed between the projection and the gullet, wherein the projection is inclined at an acute angle within a range of 64° to 79° relative to a plane extending between the tips of at least two of the teeth, wherein the projection extends from the junction radius to the gullet entry surface, wherein the projection defines an inner end adjacent to the junction radius and an outer end adjacent to the gullet entry surface, wherein the inner end is located at a depth below the tip of at least 25/1000 inch, and wherein a distance between the inner end and the outer end of the projection in a direction parallel to the plane is less than 65/1000 inch.
