That's a bunch of stripping on a fly rod. Amazing isn't it? How old you think that tip is?
I remember the first time I realized there was a line goove in a tip eye. I was fishing a tournament in Texas and thought my retrieve felt funny. Then I noticed a little fuzz on the line like abrasion from fish teeth or rocks but it was way too far away from the tag end.
I started checking things out and sure enough, my topwater rod had a goove worn into it.
I could hardly belive it. Rod was at the end of it's first season.
