The whole saw blade is made of High-Speed Steel (HSS). HSS saw blades are mainly used to cut steel, copper, aluminum and other metal materials. If high-strength steels (e.g., stainless steel) are to be cut, the blades made of cobalt HSS (e.g. M35, M42) should be used. Tungsten carbide
In creating this device, Michel effectively invented the worm-drive motor. Michel then tried again, using a piece of wood with a notch carved into it. In the notch, he mounted the same mechanism as the mechanical reaper, but with a 6-inch blade. This was the first electric circular saw.
Santiago Ramón y Cajal fathered modern neuroscience and was the first person of Spanish origin to win the Nobel Prize in Physiology or Medicine (1906).

The modern-day circular saw was invented around the end of the 18th century as a rip-saw to convert logs into lumber in sawmills and various claims have been made as to who invented it. Before the design was invented, logs were sawn by hand using a pit saw or using powered saws in a sawmill using an up-and-down saw with a reciprocating motion ...
The original company was started in 1924 by Raymond E. DeWalt, inventor of the radial arm saw. It grew quickly and was reorganized and reincorporated in 1947 as DeWalt Inc. American Machine & Foundry Co., Inc. bought the company in 1949, and sold it to Black & Decker in 1960. Black & Decker divested itself of the radial arm saw manufacturing ...
The Slinky was invented in 1943 by American engineer Richard T. James while working in his home laboratory to invent a set of springs that could be used to support sensitive instruments on board ships and stabilize them even in rough seas. When he once accidentally knocked one of his springs off a shelf, James saw that, rather than flopping in ...
A reciprocating saw is a type of handheld, small, machine-powered saw, in which the cutting action is achieved through a push-and-pull ("reciprocating") or back-and-forth motion of the blade. The original trade name, Sawzall , is often used in the United States , where Milwaukee Electric Tool first produced a tool of this type in 1951.
