Chrome/22,
It was actually a freak accident with a fish coming unbuttoned.
My buddy and his son were standing behind a bunch of us casting into a hole. I had a fish hooked for just a moment. But as I was putting the final monster pull of the hook-set, it came loose.
My pencil lead, leader and hook all came straight back at me at warp speed. I had just enough time to duck and yell "HEADS-UP" as it passed by me heading straight at my two friends.

My buddy's son was holding his rod vertically with the butt on the ground. The pencil lead hit his rod just above where the two halves come together and shattered it. It's actually a good thing that it hit his rod, because it would have hit him square in the face.
