The Ponoi Hammer was designed by Ponoi Head Guide, Max Mamaev. Max is likely to be the most successful Atlantic Salmon Guide in the world as well as being an all round fishy guy. He knows a thing or two about what makes a Ponoi salmon take a fly so it is no surprise that this is one of the most popular flies on the river.
It is not a fly limited to the Ponoi. It has proven its self where ever salmon swim, especially when the water has a slight tinge to it.
