Knot 2 Kinky Single-Strand Nickel-Titanium is a single-strand, corrosion-free leader material with a small diameter and dark color, making it inconspicuous underwater. It can stretch by 10-15% under load yet its shape remains unchanged. Unlike steel leaders, Knot 2 Kinky can be fished multiple times without having to switch. Knotting and processing the material is easy, able to be knotted well and attached to hooks or snaps with the Albright, simple clinch, or perfection loop knots (instructions on the packaging). With Knot 2 Kinky, continually changing the leader is a thing of the past!
