What does the term "gage" refer to in a band saw blade?

In the context of a band saw blade, the term "gage" specifically refers to the thickness of the blade. The thickness plays a critical role in various aspects of the cutting process, including the blade's rigidity and its ability to make precise cuts. A thicker blade is generally more rigid, which can result in straighter cuts and improved durability during operation. Conversely, a thinner blade can navigate tighter curves but may also be more prone to bending or breaking under stress.

Understanding the gage of a band saw blade is essential for selecting the proper blade for specific applications, considering factors like the material being cut and the desired cut precision. Other options, though related to blade characteristics, do not accurately define "gage." Curvature pertains to the blade's design and cutting capability, material relates to blade composition and performance, and length signifies the overall size of the blade rather than its thickness.
