PROBLEM TO BE SOLVED: To provide a reciprocating saw blade that can be used for multiple cutting applications with a single blade strip.SOLUTION: A reciprocating saw blade 20 has a blade body 22 defining a first end and a second end. A first cutting edge 28 is located on one side of the blade body 22, and a second cutting edge 30 is located on an opposite side of the blade body thereof. A first tang 24 is located at one end of the blade body 22 and defines a first acute cutting angle of the first cutting edge 28. A second tang 26 is located at another end of the blade body and defines a second acute cutting angle of the second cutting edge 30. The first and second tangs 24 and 26 are alternately and releasably engageable by the chuck of the reciprocating saw. At least one cutting edge 28 or 30 may be defined by a plurality of groups of cutting elements 36, 36, and 38, 38. Each group of cutting elements is oriented at a respective acute cutting angle relative to a tang edge that defines an effective cutting angle for that group of cutting elements. |
