Method of using a cutting blade

A method of using a cutting blade on a portable band saw, the method comprising the steps of:

• providing said portable band saw;
• providing said cutting blade on said portable band saw, wherein the cutting blade includes a plurality of sets of teeth, each set including at least one neutral tooth, one right set tooth, and one left set tooth, each tooth in the set having a linear rake face with a positive rake face angle in the range of 4 degrees to 8 degrees transitioning uninterruptedly from a tip of said tooth into a single radius ranging within the range from 0.020 inches to 0.040 inches to define a portion of said tooth and the at least one tooth has an area of 0.0025 inches squared to 0.0032 inches squared, said cutting blade having a thickness between 0.018 inches and 0.030 inches, and the set magnitude of the set teeth is between 0.007 inches and 0.012 inches, where every tooth in each set has a tip height from 0.030 inches to 0.060 inches, has a primary clearance surface having a primary relief angle, in the range of 22 degrees to 27 degrees from a line between adjacent tips of said cutting blade, has a secondary clearance surface arcuate with a radius in the range from 0.020 inches to 0.025 inches and having a secondary relief angle in the range of 30 degrees to 35 degrees from a line between adjacent tips of said cutting blade, the secondary clearance surface located adjacent to said primary clearance surface, has a tertiary clearance surface located adjacent to said secondary clearance surface, and has a tip pitch of 0.090 inches to 0.135 inches;
• using the portable band saw to cut a first object of a first material with the cutting blade, where the first material is one of wood or metal;
• and
• cutting the first object with the cutting blade of the portable band saw in a single continuous linear cut direction, and using the portable band saw to cut a second object of a second material with the cutting blade, where the second material is the other of wood or metal;
• and
• cutting the second object with the cutting blade of the portable band saw in a single continuous linear cut direction.
