Which type of saw blade is classified as a hard-edge, hard-back blade?

A blade made with one piece of heat-treated carbon steel is classified as a hard-edge, hard-back blade due to its construction and material properties. This type of blade is characterized by its rigidity and strength because it is manufactured from a single piece of steel, which contributes to its durability and ability to maintain sharpness throughout its use.

The heat treatment further enhances the blade's hardness, making it suitable for cutting through tougher materials efficiently. This design allows for a stable cutting action, minimizing deflection that might occur with more flexible blade types. In contrast, blades made with multiple components may not provide the same level of stability or cutting precision, while those made from flexible materials typically sacrifice sharpness and rigidity for versatility in different applications. Similarly, blades designed for low-speed cutting may not possess the same hard-edge and hard-back characteristics, as they often prioritize adaptability over cutting performance.
