Gamakatsu Octopus Red 25/pk. Size 4, 2, 1, 1/0, 2/0, 3/0, 4/0, 5/0, 6/0. Gamakatsu hooks are superior to all other brands for three great reasons. First, only the most premium grade of high carbon steel is used. Second, Gamakatsu has the most advanced tempering system in the world. Every hook is heated to the exact temperature that is perfect for that particular style and size then cooled in oil. This process produces hooks which are super strong, but not brittle, a balance that is difficult to achieve between strength and flexibility. Finally, and perhaps most importantly, the sharpening process is the most modern in the world, and results in a perfectly conical point that is unequaled in sharpness.
