A band saw blade (10) may include a cutting edge (14) defining a cutting plane (18) and configured to engage a workpiece during movement of the band saw blade in a cutting direction (20), and a back edge (16) located on an opposite side of the band saw blade relative to the cutting edge and defining a repeating back edge pattern (21). The back edge pattern (21) may include, in sequential order, a ramp-down section (22) defining an acute ramp-down angle relative to a plane parallel to the cutting plane, a first ramp-up (28) section defining a first acute ramp-up angle relative to the plane parallel to the cutting plane, an intermediate section (32) oriented at least substantially parallel to the cutting plane, a second ramp-up section (30) defining a second acute ramp-up angle relative to the plane parallel to the cutting plane, and a spacing section (26) oriented at least substantially parallel to the cutting plane. |
