Found another use for the string puller today. While stringing up a Tecnifiber Tflash 290 (16 main skip 7&9 t&b start throat) I found I had two string blocking hole 7t. Using the rounded edge of the point of the string puller I slipped the hook under the string so I could get grab the main going from 10t to 6t for tie off. That lifted the string up just enough to get my bottom cross in 7t easily.
I have the ability to drive people crazy, not sure if I was born with it or I learned it but I'm damn good at it.
