The water wood splitter is a complex machine for woodworking, driven by water power. It is called "Venetian" because it was introduced at the time of the Venetian Republic based on a project of Leonardo. It replaced the more basic saws with a hydraulic wheel. In the district of Seghetta in Valli del Pasubio, the Leogra waters are diverted through a ditch and conveyed on a paddle wheel.
