<p>Saw blades and methods of manufacturing saw blades. An exemplary method includes the acts of providing blade stock having a first surface and a second surface, forming a first pattern on the first surface, such as a cross-hatch pattern, forming a second pattern on the second surface, forming a first saw blade from the blade stock, the first saw blade having a first blade first surface including a first portion of the first pattern, and a first blade second surface including a first portion of the second pattern, forming a second saw blade from the blade stock, the second saw blade having a second blade first surface including a second portion of the first pattern and a second blade second surface having a second portion of the second pattern, positioning the first saw blade and the second saw blade in a position such that the first blade's first surface is adjacent one of the second blade first surface, and the second blade second surface, heat-treating the first saw blade and the second saw blade in the position, and removing from the position, after the heat-treating act, the first saw blade and the second saw blade. <IMAGE></p> |
