Abstract: A reciprocating saw blade that includes an elongated blade body defining an inner end and a distal end, a cutting edge located on one side of the blade body and extending between the inner and distal ends thereof and a tang located at the inner end of the blade body. The tang projects from the blade body at an acute angle of at least about 3° relative to a line tangent to an inner end of the cutting edge. The cutting edge includes a portion defining a substantially curved contour and optionally can include at least one further portion defining a non-curved contour.

Abstract: A saw blade comprising cutting teeth, having at least one of chip-limiters protruding from the teeth or secondary teeth in the gullets of the cutting teeth configured to mitigate the blade from over-feeding. The chip limiters and/or secondary teeth provide that only a limited portion of an object that the saw blade encounters during cutting falls below the cutting tips of the cutting teeth. The chip limiters and/or secondary teeth also assist the cutting teeth in cutting.

Abstract: A saw blade having a blade body, a plurality of cutting teeth defining a cutting edge along an edge of the blade body, each tooth along the cutting edge defining a cutting tip. At least one tooth tip along the cutting edge includes a different material, such as, for example, high speed steel, carbide, diamond, and/or a tip coating, than at least one other tooth tip along the cutting edge. The plurality of teeth may be arranged in a repeating pattern or in no pattern along the cutting edge. A method of manufacturing the saw blade includes forming a cutting edge along an axial edge of a blade body, defined by a plurality of cutting teeth having respective tooth cutting tips, wherein at least one tooth tip along the cutting edge includes a different material than at least one other tooth tip along the cutting edge.

Abstract: A reciprocating saw blade has a blade body defining first end and second ends. A first cutting edge is located on one side of the blade body, and a second cutting edge is located on an opposite side of the blade body thereof. A first tang is located at one end of the blade body and defines a first acute cutting angle of the first cutting edge. A second tang may be located at another end of the blade body and defines a second acute cutting angle of the second cutting edge. The first and second tangs are alternately and releasably engageable by the chuck of the reciprocating saw. At least one cutting edge may be defined by a plurality of groups of cutting elements. 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.

Abstract: A reciprocating saw blade, for use in a portable power reciprocating saw including a chuck for releasably engaging the saw blade, includes a tang having an elongated axis and being engageable with the chuck for attaching the saw blade to the reciprocating saw. The saw further includes a blade portion having a cutting edge that defines a plurality of cutting teeth. The cutting teeth define a repeating pattern of successive groups of teeth. Each group of teeth is less than about a half inch in length, and includes a plurality of laterally offset teeth, at least one relatively high first tooth and at least one relatively low second tooth. Prior to tooth set, the at least one relatively high first tooth is at least about 0.002 inch higher than the at least one relatively low second tooth.

Abstract: A recip saw blade has a blade body and a cutting edge extending along the blade body and defined by a repeating pattern of two consecutive teeth suitable for abusive cutting applications. The blade defines a relatively coarse tooth pitch. The two consecutive teeth, which may be bi-metal, include a high tooth and a relatively low tooth in comparison to the high tooth. Each high tooth and low tooth include a primary clearance surface defining a relatively shallow primary clearance angle that is about 28° or less, and a secondary clearance surface defining a relatively steep secondary clearance angle in comparison to the primary clearance angle. The primary clearance angle of the high tooth is steeper than the primary clearance angle of the low tooth, such as between about 23° and 28°, and the secondary clearance angle of the high tooth is shallower than the secondary clearance angle of the low tooth.

Each of the two consecutive teeth includes a primary clearance surface defining a relatively steep primary clearance angle, a secondary clearance surface defining a relatively shallow secondary clearance angle, a tip, a rake face located on the opposite side of the tip relative to the primary clearance surface, a gullet defining a depth, a first gullet radius located on an opposite side of the gullet relative to the rake face, and a second gullet radius located between the gullet and the rake face, wherein the depth of the gullet is greater than the second gullet radius.

Abstract: There is provided a device for driving a fastener, such as a nut driver, that includes an elongate shaft having a first end and a second end opposite the first end, an aperture disposed on the first end and having an interior aperture shape that is substantially the same as at least a portion of an exterior shape of the fastener, a handle disposed on the shaft, and a tactile feel element disposed on the shaft having an element shape. The element shape has an orientation that is at least substantially the same as an orientation of the interior aperture shape. There is also provided a manufacturing method.

Abstract: A multi-tool screwdriver includes a handle, a multi-tool shaft and a hexagonal-shaped sleeve. The handle defines a shaft opening therein for receiving and securing the multi-tool shaft to the handle. The multi-tool shaft includes a hexagonal shaped driver on both ends thereof, each driver adapted to receive a driver bit. The hexagonal-shaped sleeve is receivable within at least one of the multi-tool shaft drivers and includes a hexagonal shaped driver on both ends thereof, each driver adapted to receive a driver bit. An impact resistant insert is disposed within the handle to absorb impact forces and prevent the multi-tool shaft and/or bits stored in the handle from penetrating the handle when the handle is struck by a hammer or other object when the multi-tool screwdriver is used, for example, as a chisel or punch.
