The BKK SF Deep is a powerful assist hook specifically designed for heavy jigging in deep-sea conditions. This model incorporates BKK's finest technologies and is constructed from exceptionally robust materials. The hook is made from BKK's (6X) alloy, which undergoes heat treatment for added strength. Its surface is coated with Bright Tin, providing a slick texture that enhances penetration and ensures durability, while also offering full protection against saltwater corrosion. The leader material consists of a strong four-strand braided line with a hollow core. The hook’s ultra-sharp point, meticulously hand-sharpened, easily pierces the mouths of large fish. Its semi-circular shape, combined with an inward-pointing bend, reduces the chances of losing fish or experiencing missed strikes. The barb is designed to hold fish securely and helps rectify mistakes during landing. Additionally, a glow-in-the-dark thread, encased in heat shrink, attracts predators at great depths.
