This stuff is awesome. Forget the need for crimping sleeves and pliers. Tyger Steel Leader is a micro-braided stainless steel leader that can be tied. Tie it just like monofilament to your flies for toothy gamefish like pike, baracuda, sharks, sierra mackerel, etc. We recommend tying it to your leader with an Albright Knot then tie your fly on with a two or three turn Clinch Knot. It is very thin and super flexible with a nylon coating. 10 feet in each package.
