I have been using this tool for many projects, and find it quick and easy. The knots created with this tool are tighter and closer to the bead than what I could do without it. I love it!

I purchased this tool to see if it might save some time, and after working with it, I realized that my tweezer or hand methods got knot closer and tighter to the pearl than this tool. Since silk stretches some on pearls over time, this was not a good purchase for pearl stringing. Perhaps beads would be different, but at least I gave it a try. Interesting design, the YouTube video helped me learn how to use it. Just prefer other methods.
