Which part of a band saw blade is opposite the tooth edge?

The part of a band saw blade that is opposite the tooth edge is referred to as the back. This portion is typically flat and serves to provide structural integrity to the blade while preventing the teeth from becoming damaged or dulled during operation. The back is important because it fits into the band saw's wheel system, providing tension and support that facilitates smooth movement as the blade cuts through materials.

Understanding the function of the back in contrast to the teeth is crucial for maintaining the blade's performance and longevity. The other options, such as the wing and toe, do not pertain to the section directly opposite the teeth, contributing to the understanding of band saw blade anatomy.
