Italian made stainless steel serrated, v-shaped, quick-cut blade. Simply put on the rope and pull. A very useful tool for cutting any lines or net (with the exception of steel wire). Protective hooked safety end. Lanyard hole in the handle. The beauty of this is it comes with a belt or strap mountable scabbard so it is readily on hand. A must for anyone spearing high strength, large weight pelagics, where entanglement in lines may be a possibility.
