M6 fiber optics cleaver" is a tool used to precisely cut optical fibers for applications like fusion splicing. It is a manual or automatic cleaver designed for high accuracy, with a low average cutting angle of less than \(0.5^{\circ }\), and typically features a long-lasting tungsten steel blade. These models often have a versatile, multi-functional design that can cut different types of fiber, including 0.25mm bare fiber, 0.9mm pigtail, and 2.5-3.0mm leather cable.
