The Crescent Wiss MetalMaster Offset Left and Straight Cut Aviation Snips are capable of cutting left arcs and straight lines while keeping your hands away from the cut material. The CNC-serrated blades tightly hold and aggressively cut material, while the self-opening spring action delivers a smooth, low-effort feed. Non-slip cushion grips provide superior control and tough molybdenum steel blades have exceptional durability and long blade life. Cuts up to 18-Gauge carbon steel.
