A saw blade includes a body and a cutting portion coupled to an edge of the body. The cutting portion includes a plurality of cutting teeth. The plurality of cutting teeth includes a first tooth form with an abrasive grit and a second tooth form without an abrasive grit.

A machining tool (1) includes a tooth (3) having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is designed to be asymmetrical. The machining tool (1) thus is a 2-in-1 machining tool including differently designed sides of the tooth tips (4) which are suitable for efficiently machining different materials.

A bandsaw blade, including a main tooth group formed by nine sawteeth arranged in sequence, including three sub-tooth groups including a first sawtooth (1,4,7) of straight tooth, a second sawtooth (2,5,8) of left set tooth and a third sawtooth (3,6,9) of right set tooth. Each of sawteeth (1) and (4)-(6) has chamfers on two sides. Sawtooth (1) has a first height, sawtooth (4) has a second height and sawtooth (7) has a third height. Sawteeth (5) and (6) have the same fourth height. Sawteeth (2), (3), (8) and (9) have the same fifth height. The first through fifth heights are sequentially decreased. A top plane width of sawtooth (4) is larger than that of sawtooth (1). A top plane width of sawtooth (7) is larger than that of sawtooth (4). By using the bandsaw blade, more chips can be produced to reduce total cutting force and improve cutting efficiency.

A reciprocating saw blade for a machine tool, in particular a jigsaw blade, includes a first row of saw teeth and a second row of saw teeth. The first and second rows of saw teeth are arranged at an angle to a longitudinal axis of the reciprocating saw blade. The angle of the first row of saw teeth opposes the angle of the second row of saw teeth. The reciprocating saw blade also includes a further row of saw teeth arranged between the first and second rows of saw teeth. The further row of saw teeth is set back, in particular suddenly set back, towards the longitudinal axis in relation to the first and second rows of saw teeth.

A reciprocating saw blade including a body, an attachment portion, a cutting portion formed on the body including a plurality of cutting teeth, and a plunge point for initiating a plunge cut including a plunge tooth and a leading gullet between the plunge tooth and a first tooth of the plurality of cutting teeth. A first angle of the rake face of the plunge tooth is measured through the plunge tooth. A second angle of the rake face of the first cutting tooth is measured through the first cutting tooth. One of the first angle and the second angle is greater than 90 degrees and the other is less than 90 degrees. At least the first cutting tooth is set. The rake face defining the first angle is spaced from the rake face defining the second angle by a distance greater than the pitch of the plurality of cutting teeth.

The present invention describes a muscle enhancement device comprises a pad sandwiched between two pieces of fabric. The pad is surround by a transitional edge. When muscle enhancement device is being worn properly, the muscle enhancement device is changed from a relaxed state to a stretched state and pad provides a soft, comfortable diffused and obscure edge.

A reciprocating saw blade includes a body defining a longitudinal axis. The blade includes a cutting portion having a plurality of cutting teeth. Each cutting tooth includes a protrusion and a tip spaced a first distance from the protrusion. The tip of a first cutting tooth is spaced a pitch distance from the tip of an adjacent second cutting tooth. A gullet is defined between the tip of the first cutting tooth and the protrusion of the adjacent second cutting tooth. The tip of a respective cutting tooth is spaced a tip height distance from a base of the gullet. An apex of the protrusion is spaced a protrusion height distance from the base of the gullet. The protrusion height distance is 65% to 68% of the tip height distance. The first distance is 40% to 77% of the pitch distance.

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 saw blade includes a body and a plurality of cutting teeth formed on the body. The plurality of cutting teeth include a first cutting tooth having a tip adjacent a first end of the first cutting tooth, a rake face defining a rake face line extending from the tip toward the body at a positive rake angle, and a relief face extending from the tip toward a second end of the first cutting tooth. The saw blade also includes a plurality of gullets formed on the body between the plurality of cutting teeth. The plurality of gullets include a first gullet forming an undercut of the first cutting tooth. At least a portion of the undercut is positioned on a side of the rake face line in a direction opposite a cutting direction of the saw blade.
