O Mustad Tuna Inline Circle Hook - To most people the most important thing about a fish hook is its ability to catch fish, and this is of course also the most important thing for Mustad when designing and developing a hook pattern. In order to make a high-quality fish hook for a specific type of fishing, there are many parameters that have to be decided upon. Such elements decide the particular properties of an individual hook pattern and how suitable it is for a specific type of fishing. Our Tuna Circle Hooks feature an inward curved point with a ringed eye and have our Duratin coating for added corrosion resistance.
