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: should the the point be straight or bent in -- the throat be deep or shallow -- the shank be long or short -- the eye be straight, bent up or bent down -- the wire be thin or heavy ... such elements decide the particular properties of an individual hook pattern and how suitable it is for a specific type of fishing.
