Gamakatsu fishing hooks use premium grade of high carbon steel, insuring against any blemishes which can weaken the hook. Gamakatsu® claims to have the most advanced tempering system in the world. Hooks are heated to the exact temperature then cooled in oil. Producing hooks which are super strong, but not brittle. The sharpening process is claimed to be the most modern in the world, and results in a perfectly conical point. Compare to Ahrex Hooks. See our Saltwater Gamakatsu range.
