These are 1.50 inch diameter and 0.125 inch thick leather handle washers. They are commonly used for creating custom handles on hidden tang knives. Once they are stacked, they can then be compressed into a uniform handle shape. After stacking and tightening, they can be sanded into the final handle configuration. These are high quality leather parts that are punched out of top-grain cowhide in our USA facility. Once finished, they create excellent handles for knives and tools, and feature high-griping, durable surfaces. This style of handle treatment has been used throughout history and is still one of the best performing ever developed. They are noted for creating one of the most comfortable handle treatments available. This type of knife handle is also quite simple to construct, and will last a lifetime.
