A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.

A band saw blade includes a body part made into a loop in an endless form at a joint part formed by welding, a blade part formed on one edge side of the body part, a first shot blasted part formed on at least one side plane of the body part, a second shot blasted part formed in a part of the first shot blasted par and visually recognized as a range having a surface state different from a surface state of the first shot blasted part, and an information part that is provided to the second shot blasted part and from which information can be acquired.

A method of using a cutting blade on a portable band saw. The method includes the step of providing a portable band saw. A cutting blade is provided which includes at least one tooth that has a linear rake face with a positive rake face angle transitioning uninterruptedly from a tip of said cutting tooth into a single radius to define a portion of said cutting tooth. The portable band saw is used to cut and object with the cutting blade of the portable band saw in a single continuous linear cut direction.

An oscillating blade including a shank having a tool mounting end and a blade end, the shank defining a longitudinal shank axis extending from an oscillation axis of the tool mounting end, the longitudinal shank axis defining a longitudinal direction. The oscillating blade also includes a first shank extension extending from the blade end in a first lateral direction and having a first cutting edge directed in a first cutting direction, and a second shank extension extending from the blade end in a second lateral direction and having a second cutting edge directed in a second cutting direction. The oscillating blade also includes a shaving edge disposed on the blade end. The first shank extension is spaced from the second shank extension in the longitudinal direction, and the shaving edge is at least partially disposed between the first shank extension and the second shank extension in the longitudinal direction.

A recip blade has a blade body including a cutting edge and a tang located at one end of the blade body. The tang defines an arcuate cross-sectional shape or is laminated to increase the overall thickness of the tang and, in turn, enhance the rigidity of the blade and/or reduce oscillation or whipping of the blade during cutting.

A surgical saw and complementary blade. The blade has lock teeth that are more ductal than the cutting teeth. The saw coupling assembly has an anvil and a press. The saw coupling assembly holds the blade to the saw by compressing the saw lock teeth between the anvil and the press so as to result the coining of the lock teeth.

A saw blade for use with a reciprocating saw includes a body and an attachment portion extending from the body. The attachment portion includes a tang and an aperture configured to connect to the reciprocating saw. The saw blade also includes a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth and a floor guard tooth positioned adjacent at least one of the plurality of cutting teeth. Each cutting tooth has a tip that defines a plane. The floor guard tooth extends from the body beyond the plane. The attachment portion is offset from the plane to reduce interference of the reciprocating saw with a surface while performing a footer cut with the saw blade. The floor guard tooth contacts the surface while performing the footer cut to inhibit the plurality of cutting teeth from contacting the surface.

A reciprocating saw blade includes a body defining a longitudinal axis. The saw blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face at least partially defining a gullet, a relief surface, and a protrusion extending from an end of the relief surface. The protrusion of each cutting tooth inhibits a nail from entering the gullet. The tips of the plurality of cutting teeth define a first plane that is generally parallel to the longitudinal axis and the protrusions of the plurality of cutting teeth define a second plane that is generally parallel to the longitudinal axis. A distance between the first plane and the second plane is at most 0.035 inches, and a distance between the protrusion of one cutting tooth and the tip of an adjacent cutting tooth, measured generally parallel to the longitudinal axis, is 0.08 inches.

A blade for oscillating tools includes lateral edges, a working edge that extends in a first direction, and a mounting portion. The mounting portion includes a first mounting configuration that defines a first center and a second mounting configuration that defines a second center, where the first center is spaced a distance away from the second center in a direction that is substantially orthogonal to the first direction in which the working edge extends or to a tangent of a center of curvature of the working edge. Both mounting configurations are configured to drive the same working edge.

A reciprocating saw blade has a first end with a first tang and a second end with a second tang. The first and second tangs are alternatively engageable with the chuck of a reciprocating saw. The reciprocating saw blade defines a substantially uniform cutting edge extending from approximately the first end to approximately the second end of the blade. The first tang is engageable with the chuck of the reciprocating saw for fixedly securing the first end of the blade to the reciprocating saw and forming with the second tang the free end of the saw blade. Alternatively, the second tang is engageable with the chuck of the reciprocating saw for fixedly securing the second end of the blade to the reciprocating saw and forming with the first tang the free end of the reciprocating saw blade drivable in a reciprocating motion by the reciprocating saw.
