Knife-making is a craft that requires precision and patience. One of the most important steps in creating a quality knife is sanding. Sanding helps to refine the blade's edge and shape, creating a sharp and polished finish. However, not all sanding belts are created equal. In this article, we will discuss the pros and cons of different types of sanding belts used for knife making.
