In 1966, Mr. Ishii, a Chemical Engineer employed in the researcher division of Kureha, Japan, and Mr. Yoshida, and avid angler working in the Patent Department of Kureha, Japan, noticed that the attributes of Fluorocarbon were ideally suited to fishing line. The men saw that Fluorocarbon is less absorbant than nylon monofilament, impervious to UV rays, high-density and nearly invisible underwater. They knew early on...Fluorocarbon would revolutionize fishing line! And so the two men applied for a patent, which was granted and registered in 1969.
Seaguar continues to develop and perfect the art of 100% Fluorocarbon Leader, Tippets and Main Line.
