Circular saws and saw blades are used in saw mills. Here's a brief history (from Wiki) of the invention of the circular saw blade.
A Southampton man, Walter Taylor, in 1762 built a saw mill. Wiki says: "Descriptions of his machinery there in the 1790s show that he had circular saws."
A sailmaker called Samuel Miller, also of Southampton obtained a patent in 1777 for a saw windmill. However the specification for this only mentions the form of the saw incidentally, probably indicating that it was not his invention.
Three years later in 1780 a man called Gervinus in Germany invented the circular saw.
A large circular saw in a saw mill is said to have been invented in 1813 by Tabitha Babbitt after she noted the inefficiency of the traditional saw pits used by the sawyers in her community and sought an improvement - athough, it says on Wiki, that this is now mostly discredited.
