A saw blade includes a main body having a first surface, a second surface on an opposite side of the main body from the first surface, a proximal edge portion, a distal edge portion, and first and second side portions extending between the proximal and distal edge portions. The proximal edge portion is configured to be coupled to a rotatable hub such that the saw blade is held in a curved shape with the first surface defining an outer radius when the saw blade is coupled to the rotatable hub. The distal edge portion includes a plurality of cutting teeth, and the second surface includes a cutting structure configured such that a radius of an arc swept by the cutting structure when the saw blade is rotated is substantially equal to the outer radius of the first surface.

Devices, systems, and methods for a segmented tool include a connection system for selectively connecting segments together for use. The connection system can be collectively formed of complementary portions of the segments which can be interlocked together to block against disconnection.

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 saw blade including a body and a plurality of teeth disposed on the body and defining a cutting portion. At least one tooth of the plurality of teeth have a substrate forming a tip of the at least one tooth. The saw blade further includes a thin film ceramic coating overlaying at least the substrate. The thin film ceramic coating has a greater strength than the substrate.

The present disclosure provides a multi-edge saw blade for use with an oscillating tool that provides multiple cutting edges that can be used sequentially as each cutting edge becomes worn-out or damaged. The multi-edge saw blade includes a first row of cutting teeth arranged across its distal edge and a row of perforations situated across the distal end of the blade and spaced a distance behind the first row of cutting teeth. In some aspects, the multi-edge saw blade further includes at least one additional row of perforations, each situated a spaced distance behind the row of perforations before it. Responsive to a twisting force applied orthogonally to the plane of the blade, each blade edge can be removed from the blade to reveal a fresh row of cutting teeth. The multi-edge saw blade further includes an attachment socket on its proximate end.

A saw blade including a body, a plurality of cutting teeth, and a plurality of gullets. The plurality of cutting teeth formed on the body. Each cutting tooth includes a first end and a second end. The plurality of gullets is formed between the plurality of cutting teeth. Each gullet having an opening defined between the first end of one tooth of the plurality of cutting teeth and the second end of an adjacent tooth of the plurality of cutting teeth. Each opening has an opening width and a gullet width. A ratio between he gullet width over the opening width is greater than or equal to 1.2:1.

A saw blade including a body, a plurality of cutting teeth, and a plurality of gullets. The plurality of cutting teeth formed on the body. Each cutting tooth includes a first end and a second end. The plurality of gullets is formed between the plurality of cutting teeth. Each gullet having an opening defined between the first end of one tooth of the plurality of cutting teeth and the second end of an adjacent tooth of the plurality of cutting teeth. Each opening has an opening width and a gullet width. A ratio between he gullet width over the opening width is greater than or equal to 1.2:1.

A saw blade includes a blade body having a top surface and a bottom surface, wherein the blade body is at least partially comprised of a first composite material or a metal; a cutting edge on a distal end of the blade body; and a coupling configured to connect the blade body to a handpiece adapted to oscillate the blade body. The saw blade may include: a first inlay portion and a second inlay portion, where the first inlay portion is either embedded in the top surface or covers the top surface, and the second inlay portion is either embedded in the top surface or covers the bottom surface; or an inlay portion sandwiched between a top portion and a bottom portion of the blade body.

A saw blade includes a body and a plurality of cutting teeth formed on the body. Each cutting tooth includes a tip at a first end of the cutting tooth, a rake face extending from the tip toward the body, a relief face extending from the tip toward a second end of the cutting tooth and sloping toward the body, and a projection at the second end of the cutting tooth and sloping away from the body. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. Each gullet forms an undercut portion between the body and the projection of each cutting tooth.

A surgical saw blade including a cutting edge, blade body and a coupling for connecting the blade body to a handpiece. The blade body at least partially includes a composite material that helps to confer optimal weight and rigidity to the saw blade to allow for minimal vibration during use and minimal mechanical load on the handpiece.
