This happend July 30th of last year(2008) on long island new york. apparently the guy was snagged in the rocks and when he tugged on his line to get the sinker back it launched out of the water, entering his skull next to his eyeball and cutting his brain stem! i feel this would be an awesome myth for the guys to do!

The force of the sinker caused severe head trauma and herniation to the man’s brain.
I really can’t even picture how this could happen. I have done a lot of fishing and I don’t ever recall hitting myself with the sinker. Sure, I have lodged a fishing hook in the back of my head, my back, and my hand, but who hasn’t? Hooks are a bit different than sinkers. They have points.
It just goes to show you that lead sinkers are not only a cause of concern for the environment and wildlife, but if not in the right hands, they can also lead to a tragically weird death. Just something to think about next time you are casting away-

I'd say this is very plausible. Depending on how hard you have to pull to get your line unstuck and the elasticity of the fishing line you are using the sinker could come back with a lot of force. All it takes is that chance that it hits in exactly the right spot. If you feel around your eyes, you will notice that there is some space that is not protected by bone/cartilage. A sinker with enough velocity could easily penetrate that space and enter your brain.

Sinkers are generally quite heavy, since they are designed to keep the line taut while fishing.

So a flying sinker with a great deal of kinetic force in it would be a dangerous thing...

The weight of a sinker depends on its use though.. it can be ranging from 1/32 of an ounce to several pounds or more..

good explanations fellow busters! from speaking with the conservation officer who responded he told me it was a 3oz pyramid sinker and 50 pound mono filament can stretch to about 25% of its original length, im not good with math could someone do the math
how much energy is stored in 50 pound mono filament stretched to 25% its original length
