The ultimate new braid in the J-Braid family, Daiwa J-Braid Grand x8 is some of the strongest and most abrasion resistant 8-carrier braided fishing line ever put on the market. Yet, despite its durability, J-Braid Grand x8 is also extremely soft, supple, and easy-to-spool. How is fishing line with such remarkable characteristics possible? J-Braid Grand x8 is spun with IZANAS, a new, state-of-the-art, high-modulus fiber that is leaps and bounds stronger than any other fiber material on the market. Now, you may be asking yourself: "Hey, doesn't every fishing line claim to be the strongest, most supple line out there? How is this stuff any different?" And you wouldn't be wrong for wondering. Many a fishing line company has made such a claim with little, if any, evidence to support it. But the fine folks at Daiwa don't play like that: when they make a claim, they stick by it and back it up. And that's why in the graph below you can see that, when compared with other fiber materials on the market, nothing exhibits a strength index quite like IZANAS. Source: Toyobo Industrial Materials, 2018 It's roughly four times stronger than polyester nylon (what most monofilament is made of), twice as strong as fluorocarbon, and is even stronger than aramid, a class of military- and aerospace-grade fibers that includes Kevlar (aka the stuff bulletproof vests are made of), among others. Island Blue J-Braid Grand x8 is a bright blue color that offers high visibility while also incorporating sky and water contrast.
