Double sided hand hack saw blade and method of manufacture

A double-sided hand hack saw blade comprising:

• a blade body defining a first end and a second end and a length extending from the first end to the second end;
• and
• first means for cutting located on one side of the blade body defining a first wavy set pattern and second means for cutting located on an opposite side of the blade body defining a second wavy set pattern;
• wherein the first wavy set pattern and the second wavy set pattern each define a maximum set magnitude that are substantially the same as each other and aligned at a same point or location along the length of the blade body relative to a reference point, and are either (i) timed with each other so that the aligned maximum set magnitudes are set in a same direction as each other or (ii) approximately 180 degrees out of phase with respect to each other so that the aligned maximum set magnitudes are set in opposite set directions from each other.

A method of manufacturing a double-sided hand hack saw blade comprising the steps of:

• mounting at least one blade body defining a first end and a second end and a length extending from the first end to the second end in a milling fixture;
• milling first and second cutting edges defined by a plurality of teeth along opposing edges of the at least one blade body;
• removing the at least one blade body from the milling fixture and placing the at least one blade body into a setting die;
• and
• substantially simultaneously setting the teeth on the first and second cutting edges and, in turn, forming a first tooth set pattern of teeth on the first cutting edge and a second tooth set pattern of teeth on the second cutting edge;
• wherein the first tooth set pattern and the second tooth set pattern each define a maximum set magnitude that are substantially the same as each other and aligned at a same point or location along the length of the blade body relative to a reference point, and are (i) timed to each other so that the aligned maximum set magnitudes are set in a same set direction as each other;
• or (ii) approximately 180 degrees out of phase with respect to each other so that the aligned maximum set magnitudes are set in opposite set directions from each other.
