What defines the back of a band saw blade?

The back of a band saw blade is defined as the surface that is opposite the tooth edge. This is an important characteristic because the back provides the necessary support and structure for the blade while being used in cutting operations. It is crucial for the blade's stability and helps to maintain the proper alignment during cutting, ensuring precise and clean cuts.

In contrast, the tooth edge is where the actual cutting action occurs and comprises the sharp teeth that engage with the material being cut. Other elements such as flexibility can be present in various blades, but the defining feature of the back specifically relates to its position opposite the cutting teeth. This distinction is vital for understanding band saw blade construction and functionality in metal cutting applications.
