    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 ...

  3. Scroll saw - Wikipedia

    en.wikipedia.org/wiki/Scroll_saw

    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 ...

  4. Jigsaw puzzle - Wikipedia

    en.wikipedia.org/wiki/Jigsaw_puzzle

    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. [6] Wooden jigsaw pieces, cut by hand

  5. Fretsaw - Wikipedia

    en.wikipedia.org/wiki/Fretsaw

    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 ...

Ipe lets users draw geometric objects such as polylines, arcs and spline curves and text. Ipe supports use of layers and multiple pages.

  8. Freeform surface modelling - Wikipedia

    en.wikipedia.org/wiki/Freeform_surface_modelling

    Freeform surface modelling is a technique for engineering freeform surfaces with a CAD or CAID system.. The technology has encompassed two main fields. Either creating aesthetic surfaces (class A surfaces) that also perform a function; for example, car bodies and consumer product outer forms, or technical surfaces for components such as gas turbine blades and other fluid dynamic engineering ...

  9. Snips - Wikipedia

    en.wikipedia.org/wiki/Snips

    There are two main types: straight-pattern and duckbill-pattern. Straight-pattern is best for straight cuts, but can handle gentle curves. Duckbill-pattern snips, also known as trojan-pattern snips, have blades that taper down from the pivot to the tip of the blades. The blade edges are also bevelled to more easily cut curves and circles or shapes.
