The Frabill Line Saber Line Cutter cuts monofilament, fluorocarbon, superbraided, and braided tip-up lines with ease. These line cutters feature a white LED light. This light is great for illuminating the cutting area as well as charging glow lures. The single LED light is also very handy when it comes to finding dropped items in the boat or on the ice. The twist on switch mechanism prevents accidental activation, extending the battery life. Replaceable standard lithium coin battery.
