A saw is a manual or powered cutting tool designed to sever material along a designated line of cut. Functionally, the tool operates by transmitting mechanical force through a fine-toothed blade across the workpiece. The effectiveness of the cut depends on the material being cut, the geometry of the blade, and the application of controlled pressure. Various types of saws are specialized for different applications, ranging from cross-cutting rigid structural components to precision shaping of softer materials. The design principles often involve optimizing the tooth geometry and pitch to maximize the rate of material removal while minimizing excessive strain on the cutting edge.
