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 circular saw was connected to a water-powered machine to reduce the effort to cut lumber. [ 4 ] [ 5 ] The first circular saw she allegedly made is in Albany , New York . [ 6 ] In the summer of 1948, a version of Babbitt's saw, built to her specifications, was on display at a Shaker exhibit at Fenimore House in Cooperstown, N. Y., as a loan ...

Technological development helped the industry meet the soaring demand. New methods of transporting lumber, like the steam engine, provided the means to log further inland and away from water. New machines such as the circular saw and the band saw allowed forests to be felled with significantly improved efficiency. [45]
