ABSTRACT:
A saw blade with cutting wings on the teeth. The blade has a blade body, teeth located on an outer edge of the blade body, and cutting wings extending from either side of each tooth on the blade body. Each tooth is angled in a direction opposite that of the adjacent teeth to eliminate block cutting characteristics and to enhance the serrating effect of the teeth. A first wing is longer than a second wing and contains a barb that enhances the serrating effect of the wing. Both wings are beveled so that the sharpest edge of the wings is located on the outer edge of the wings. The cutting wings pre-cut a width of the material and reduce the splintering and shredding effects of the blade on the material.
