Of course, if you are serious, these are not trivial questions. These are two of the things that revolutionalized fly rod building in the later half of the 20th Century.

First, what year was the first graphite fishing rod made? What company made it?

Second, though I know the answer to the first, I do not know the answer to this one. When was the first self ferruling blank made or "commercially produced" if you wish? Again, what company?

Big atta boys to the first to get both answers, though you will have to cite a source for the second one.

BTW what other revolutionary things do you think affected the construction of fly rods over the last 50 years.
