STROFT NiTi Monowire

Predator leaders made from nickel-titanium alloys (NiTi) are becoming increasingly popular – mainly due to their unique property of returning to their original state even after severe bending. However, problems sometimes arise when "connecting" these nickel-titanium wires to swivels, snap hooks, etc. – the breaking strength often fluctuates greatly! This is due, on the one hand, to the sharp edges of the crimp sleeve used. If this crimp sleeve is squeezed too tightly, there is a risk of a notching effect at the end of the sleeve, and thus a risk of reduced breaking strength. On the other hand, if the crimping is too weak, there is a risk of slippage, which also leads to a reduction in breaking strength.

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 crimp sleeves, no crimping pliers – a simple, easy-to-tie clinch knot with 4 turns is the solution – and with STROFT NiTi (for thinner wires), it can even achieve a breaking strength of up to 100% of the linear breaking strength!!!

This was made possible by a very targeted adjustment of the alloy composition to the properties desired for predator leaders – namely: highest bite resistance, superelasticity, optimal (simple) knotability, best possible shape memory, highest breaking strength/highest knot breaking strength, sufficient elasticity (8%), and reflection-free surface. STROFT NiTi Monowire and STROFT NiTi Polywire optimally fulfill all these properties. For example, a 0.20 STROFT NiTi Monowire has a breaking strength of 4.2 kg, which is almost achieved even with a clinch knot!

The Monowire is generally stiffer than the Polywire, which consists of several individual wires.

Therefore, if you want to use the clinch knot, you should choose STROFT Polywire from a diameter of 0.30 mm (because STROFT Monowire then becomes quite stiff).

The clinch knot with STROFT Polywire is still easy to tie even with a diameter of 0.60 mm.

However, if 0.35mm or 0.40mm STROFT Monowire must be used (for example, if a very stiff leader is desired), then crimp sleeves are advisable. To minimize the aforementioned disadvantages of crimp sleeves, it makes sense to "de-sharpen" the relatively sharp inner edge of the crimp sleeve beforehand (e.g., with a 90-degree countersink). Afterward, a heat shrink tube should be pulled over the crimp sleeve to reduce the kinking effect at the sleeve. Of course, the clinch knots can also be covered with a heat shrink tube, although this is not necessary for reasons of breaking strength – but perhaps for optical or practical reasons. For example, the snagging of water plants can be reduced.
