EZ Knotting Tool by Beadsmith,
Knotting tool creates secure, uniform knots.
Useful for stringing pearls and other types of beads. Includes instructions and diagrams.
Benefits: if the string breaks, only one bead can fall off. Beads will not rub together and damage each other.
The knots help maintain even spacing between beads, & reduce wear on string from bead movement. Needle is sharp, please use with caution.
