The offset blade may be used a reciprocating saw. | 03-03-2016 |
| 20160114416 | BAND SAW BLADE WITH REPEATING BACK EDGE PATTERN AND RELATED METHOD - A band saw blade may include a cutting edge defining a cutting plane and configured to engage a workpiece during movement of the band saw blade in a cutting direction, and a back edge located on an opposite side of the band saw blade relative to the cutting edge and defining a repeating back edge pattern. The back edge pattern may include, in sequential order, a ramp-down section defining an acute ramp-down angle relative to a plane parallel to the cutting plane, a first ramp-up section defining a first acute ramp-up angle relative to the plane parallel to the cutting plane, an intermediate section oriented at least substantially parallel to the cutting plane, a second ramp-up section defining a second acute ramp-up angle relative to the plane parallel to the cutting plane, and a spacing section oriented at least substantially parallel to the cutting plane. | 04-28-2016 |
