The methods used to create Gamakatsu hooks are what make them superior to all other brands.

First, only the most premium grade of high carbon steel is used as to ensure protection against any blemishes in the metal that can weaken the hook.

Secondly, 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.
It is extremely difficult to achieve a balance between strength and flexibility, and it took many years for Gamakatsu to perfect this process.

Finally, and perhaps most importantly, their sharpening process is the most modern in the world, and results in a perfectly conical point that is unequalled in sharpness.
