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 ...
A scroll saw is a small electric or pedal-operated saw used to cut intricate curves in wood, metal, or other materials. The fineness of its blade allows it to cut more delicately than a power jigsaw, and more easily than a hand coping saw or fretsaw. Like those tools, it is capable of creating curved cuts with angled edges, by tilting its table ...
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]
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.

Although the coping saw is often used for similar work, the fretsaw is capable of much tighter radii and more delicate work. It has a distinctive appearance due to the depth of its frame (typically between 10 and 20 inches (25 and 51 cm)), which together with the relatively short five-inch (13 cm) blade makes this tool appear somewhat out of proportion compared with most other saws.
A coping saw is a type of bow saw used to cut intricate external shapes and interior cut-outs in woodworking or carpentry. It is widely used to cut moldings to create coped rather than mitre joints. It is occasionally used to create fretwork though it is not able to match a fretsaw in intricacy of cut, particularly in thin materials. Coping saw ...
Some formats have additional support through Inkscape extensions, including PDF, EPS, Adobe Illustrator, Dia, Xfig, CGM, sK1 and Sketch. The predecessor of Inkscape was Sodipodi. Ipe lets users draw geometric objects such as polylines, arcs and spline curves and text. Ipe supports use of layers and multiple pages.
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]
