PROBLEM TO BE SOLVED: To provide a band saw blade with a repeating back edge pattern and a related method which resolve problems of the prior art.SOLUTION: A back edge 16 of a band saw blade 10 includes a repeating back edge pattern 21. The back edge 16 includes a plurality of back edge patterns 21 arranged in a repeating serial manner along the circumferential length of the band saw blade 10. The back edge 16 includes 3, 4, 5, 6, 7, 8, 9, 10 or more back edge patterns 21. The back edge pattern 21 may include, in sequential order: (i) a relatively short ramp-down section 22; (ii) a relatively long ramp-up section 24; and (iii) a relatively long spacing section 26.SELECTED DRAWING: Figure 1 |
