Offering the strongest thread and the widest gap compared to any tournament approved circle hook, the 8386BS TUNA CIRCLE 360 Tournament VMC hooks with swivel are designed to optimize the percentages of hooks when trolling or drifting live bait. Made of high quality Vanadium® steel, the 8386BS TUNA CIRCLE 360 VMC® hooks with swivel are equipped with chemically sharpened tips. To create an ultra strong needle tip, VMC uses a unique quenching process to compress the fibers into a conical shape instead of grinding them. This process ensures that each VMC® hook provides effortless penetration and resists the pressure exerted by braided lines. Imagine a hook made specifically for salt water with ultra-thin black finish layers to withstand the harsh conditions of the marine environment.
