Abstract
A saw blade is stamped with a circumferential edge. At least one gullet and shoulder are formed in the circumferential edge. Likewise, a tooth pocket is formed in the circumferential edge. The tooth pocket is defined by a wall, generally radial to circle, on the shoulder, and a shelf substantially perpendicular to the wall. A tooth is secured, ordinarily by brazing, in the pocket such that a portion of the shelf extends beyond the front face of the tooth towards the gullet so that the tooth can be brazed along its entire lateral edge such that resultant forces in the tooth are transmitted to the body of the blade. After the tooth is positioned into the tooth pocket, the tooth, as well as a projection of the blade shoulder, are ground off so that the tooth and shoulder are flush with one another. Thus, the tooth longitudinal edge is in complete contact with the shoulder wall maximizing its strength.
