Nickel-titanium wires - alloys (NiTi) are becoming increasingly popular in the predatory fish sector - mainly because of their unique property of returning to the old state even after strong bends. However, there are also disadvantages - namely when "connecting" these nickel-titanium wires with swivels, carabiners, hooks and others. Clamping sleeves are often used for this purpose. But unfortunately, these connections have greatly fluctuating load capacity values, also because of the sharp edge of the clamping sleeve. If the clamping sleeve is squeezed too much, there is a risk of notching at the sleeve end (NiTi wires are generally more susceptible to notch action than steel wires), and this could reduce the load capacity. If the squeezing is too weak, there is a risk of slipping, which also leads to a reduction in load capacity. Some companies also recommend a "knot". However, depending on the wire properties, only strongly fluctuating knot carrying forces are achieved. In addition, with thicker mono wires, the stiffness is so great that knotting becomes very difficult. STROFT NiTi Monowire and STROFT NiTi Polywire solve these problems and are therefore the first choice when it comes to the ultimate predator leader. The connections are quick and easy to make. No additional clamping sleeves, no crimping pliers - a simple, very easy to tie clinch knot with 4 turns (see image) is the solution - and this can even achieve a load capacity of up to 100% of the linear load capacity with STROFT NiTi (with the thinner wires). This was made possible by a very targeted adjustment of the alloy composition to those properties desired for predatory fish leaders - namely: highest bite resistance, super elasticity, optimal (easy) knotability, best possible shape memory (memory), maximum load capacity/maximum knot carrying force, sufficient elasticity
