Theresa called and asked me to test out this latch hook. I agreed thinking what did I have to lose. Best latch hook I've ever used! I'm 64 and have been doing latch hook for many years. We all know that eventually the hand holding the tool starts to cramp a bit. Not with this one! One day I actually put in 1,600 pieces of yarn without any cramping. The fingers that held the yarn were sore, but not the hand holding the latch hook. Wouldn't use anything else now.
