What type of machine did Leonardo da Vinci design to cut wood using a powered blade?

Leonardo da Vinci designed a hydraulic saw to cut wood using water-powered motion.

The concept used flowing water to drive a mechanism that moved a saw blade, reducing the need for continuous manual sawing. Leonardo’s studies of rivers, mills, and hydraulic power led him to explore ways natural water movement could perform repetitive industrial work.

A hydraulic saw is different from a circular saw or band saw because its defining feature is the power source and transmission system, not simply the blade’s shape. Leonardo’s design belongs to a wider family of water-powered machines that included mills, pumps, and lifting devices.

The drawing should not be treated as proof that Leonardo operated a modern sawmill. Many of his machine studies were proposals or experiments recorded on paper. Their importance lies in the mechanical principles they combine: water power, cams, linkages, and reciprocating motion.
