*	Notice that Mustad has enlarged the size sortiment. 80525 is a really good hook for Salmon, Sea trout/Brown trout, Grayling and Rainbow/Steelhead. I prefer the smaller size 12 - 16.

How to use the information above ? For example the Salmon Fly Hook Double 80525 BL. In that serial there are 9 hooks. Now we know that the length is in the interval 3.85 - 1.20 centimetre. So then, 3.85-1.20 = 2.65   2.65:9 = 0.29   We can roughly say that the difference between each hook is 3 millimetre. Size 16 = 1.2 cm, size 14 = 1.5 cm, size 12 = 1.8 cm ...etc. This method can also be used for other interval.





Finally. The Body length / Shank length (the size from the eye to the point where the hook starts to bend). You can approximately estimate it beeing 70% of the hook length for most of the hooks above, or at least concerning the nine 80525-hooks.





The interval for MB-Test The Mustad Bending Test coeffecient measured in kilograms is the maximum load the hook can withstand. (In a real fishing situation many factors influence the load a hook can take : the water, type of fish, line, rod and gear. And above all, your own experience and skill. Normally, the weight of a fish can exceed the MB Test figure many times. The MB Test enables you to tailor your equipment based on your own fishing skills).
