Ergo two-component handles: thermoplastic surface on hard polypropylene for a better grip. Side cutter developed as part of the Ergo process. Suitable for cutting copper, iron, and piano wire. Reduced distance between joint and cutting edge for maximum cutting capacity with a small opening width of the handle. Patented opening spring integrated in the handle with on/off function. High-performance high-speed steel. Phosphated, anti-rust treated. Progressive cutting edges: the cutting radius runs along the edges to cut hard materials (such as piano wire) close to the joint and soft materials (such as copper and plastic-insulated wires) at the tip. Screw connection for excellent cutting performance and cutting edge accuracy. Slim, rounded jaws for improved access to hard-to-reach areas. Induction-hardened cutting edges. Maximum working comfort with minimal effort thanks to ergonomic design. Comfortable two-component handles for optimum grip. Optimized joint position for greater leverage and improved cutting efficiency. Handles open automatically when the spring is activated.
