A saw blade is a circular cutting tool featuring teeth around its edge, mounted on a rotating arbor for efficient and precise cutting, slotting, or shaping of various materials. Its performance is fundamentally determined by the tooth tip material, body design, tooth geometry, and heat treatment process.  As a fundamental tool in modern manufacturing and processing industries, the selection of a saw blade directly impacts cutting efficiency, finish quality, and cost control.

A band saw blade is a flexible, continuous loop cutting tool installed on the driving and driven wheels of a band saw machine.

A brush cutter blade is a rotating cutting attachment mounted on the drive head of a handheld or backpack brush cutter, designed for clearing weeds, brush, saplings, and tall grass.

A riving knife is a critical safety device installed behind the saw blade on a table saw, panel saw, or sliding table saw.
