In accordance with one embodiment, an integrally formed saw blade includes a cutting edge extending along an axis from a distal front tip to a proximal rear portion, the cutting edge includes a portion with cutting teeth and a portion with no cutting teeth. A lateral edge extends along the axis from the distal front tip of the saw blade to the proximal rear portion of the fixing shank. A blade portion, with a maximum height defined by the cutting edge and the lateral edge, terminates at a corner. A fixing shank with a maximum height defined by the cutting edge and the lateral edge that is shorter than the blade portion terminates at the cutting teeth. A transition region extends from the fixing shank to the blade portion, and at least two spaced apart impressions are formed in the transition region but do not extend into the blade portion.

A cutting blade includes a body defining a longitudinal axis, an attachment portion coupled to the body, the attachment portion configured to be coupled to a power tool, and a cutting portion extending along an edge of the body parallel to the longitudinal axis, the cutting portion including a plurality of cutting teeth. Each cutting tooth includes a tip and a rake face extending from the tip, and each cutting tooth also includes a carbide insert that forms at least the tip of the cutting tooth. At least part of the cutting portion is deflectable relative to the body.

A bandsaw having a shaped band blade, at least one pair of flywheels (5, 6) arranged to move the shaped band blade; a motor member (7) connected to at least one flywheel of the pair of flywheels; a bench (8) for supporting and feeding at least one object to be cut, wherein the shaped band blade (1) has a band having a variable width between an area (2) of minimum width and an area (3) of maximum width.

A cutting blade with multiple body inserts, each comprising a load-sharing member and a flexible perimeter joint. These inserts reduce the magnitude of frictional forces acting on the blade's body. The load-sharing member, in particular, acts as a point contact between the material being cut, such as bone, and the cutting blade. As such, the frictional forces exerted act only on the load-sharing member as opposed to the entire body. By limiting the real contact area, the magnitude of friction generated during operation is reduced. Additionally, the load-sharing members create a thermally insulating space between the body and the material being cut. The functionality of these body inserts, however, relies on the flexible perimeter joint. The flexible perimeter joint isolates the effects of frictional forces to the load-sharing member by preventing direct contact between the load-sharing member and the surrounding body.

An oscillating blade for cutting or shaping sheet materials such as drywall, with a blade, a sharing portion, a depth gauge for determining depth of cut, a caliper portion for premarking sheet materials for a standard dimension cut, and a reverse direction blade.

A blade extension for a reciprocating saw comprises a movable member and a stationary member. The movable member has a proximal end, a distal end and a body extending between the proximal end and the distal end. The proximal end comprises a blade end shaped to be received in a blade holder of the reciprocating saw. The distal end is configured to be coupled to a reciprocating saw blade. The stationary member extends along at least a portion of the movable member and supports the movable member for movement relative to the stationary member. The stationary member has a proximal end configured to be coupled to the reciprocating saw and an opposite distal end. The distal end of the movable member is arranged to protrude distally beyond the distal end of the stationary member.

A saw band (1) includes a chamfered tooth (10) including two effective cutting edge portions (7) being arranged in the region of the chamfer (15) between which an ineffective cutting edge portion (8) of the first tooth (10, 11) is formed. In this way, five cutting channel portions (18) are formed by only two geometrically differently designed teeth (10).

A reciprocating saw blade for improving vibration and cordless runtime includes an elongated body having a front end portion and a rear end portion. An elongated cutting edge extends from the front end portion to the rear end portion and defines a longitudinal axis. An opposite non-cutting back edge extending from the front end portion to the rear end portion. The body has a thickness of approximately 0.89 mm to approximately 1.15 mm. A tang coupled to the rear end portion is configured to be coupled to a tool holder of a powered reciprocating saw. The cutting edge comprises a plurality of teeth and gullets. The teeth have a kerf width of approximately 1.29 mm to approximately 1.56 mm and are arranged in a pattern of alternating tooth pitch of a smaller first tooth pitch and a larger second tooth pitch.

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.

A surgical sagittal saw with a complementary blade. The blade is formed with a void to receive a pin associated with the saw that releasably holds the blade to the saw. The blade and the pin have complementary tapered surfaces. When the tapered surface of the pin moves against the tapered surface of the blade, the blade is urged against a static surface of the saw.
