What would cause a heavy tuna rod that was built with a bent butt to shear off at the ferrule? This question was asked of me by a angler that was fighting the fish while the rod was inserted into the gunnel of the boat. What kinds of reason would the rod shear off at this location where presumably it is the strongest part of the rod? Can the method of installation of the ferrule be at fault? This is not a rod that I built but I have used this blank on many builds with bent butts without incidence of breakage. I do follow a very regimented method of connecting the ferrule on these heavy tuna rods and I am very curious as to what caused the rod to shear at this location. My guesses are that it is possibly defective blank, pre-existing damage unrelated to the fishing or defective method of installation of the ferrule. From the video, I can eliminate angler error and high sticking. The breakage does not look like it was crushed but looks like it was sheared.
