A power jigsaw Battery-powered jigsaw T-shank blades. A jigsaw is a reciprocating saw that can cut irregular curves, such as stenciled designs, in wood, metal, or other materials. Jigsaws first emerged in the 19th century [1] and employed a treadle to operate the blade, which was thin and under tension, being secured at both ends to an ...
The name "jigsaw" came to be associated with the puzzle around 1880 when fretsaws became the tool of choice for cutting the shapes. [1] Along with fretsaws, jigsaws and scroll saws have also been noted as tools used to cut jigsaw puzzles into pieces. [6] The term "jigsaw puzzle" dates back to 1906.

Compass saws have a narrow, tapered blade usually ending in a sharp point, typically with a tooth pitch of 2.5 to 3 mm (eight to ten teeth per inch), [2] but down to 1.3 mm (up to 20 teeth per inch) for harder materials and as long as 5 mm (as few as five teeth per inch) for softer materials. [1]
Jigsaw may refer to: Jigsaw (tool) , a reciprocating saw that can cut irregular curves Jigsaw puzzle , a tiling puzzle that requires the assembly of interlocking pieces
A cutting or fretwork table, also known as a V-board, made of either wood or metal and which clamps to the edge of the workbench, may be used to support the work piece whilst allowing clearance for the saw blade by means of a V-shaped slot cut into it. The blade is usually clamped into position using a pair of wingnuts. Although wing nuts are ...
Offset curves are important, for example, in numerically controlled machining, where they describe, for example, the shape of the cut made by a round cutting tool of a two-axis machine. The shape of the cut is offset from the trajectory of the cutter by a constant distance in the direction normal to the cutter trajectory at every point. [6]

These curves can also be constructed using circular arcs centered at crossings of an arrangement of lines, as the involutes of certain curves, or by intersecting circles centered on a partial curve. Every body of constant width is a convex set , its boundary crossed at most twice by any line, and if the line crosses perpendicularly it does so ...
