Sometimes erroneously called crimp beads, bead tips are jewelry findings that provide a great way to hide knots on your bead thread. To use a bead tip, thread the end of your stringing material through the hole then knot it to secure your strand. Bend the hook closed to create a simple loop for attaching your clasp.
Clam-shell (fold-over) bead tips allow you to completely cover the knot by folding the clam-shell down over the knot before creating your loop.
Secure fold-over bead tips include an already-closed loop.
The difference between bead tips and crimp beads is that crimp beads are actually crimped down onto your cable or thread to create a secure hold (best for stringing materials that can't be knotted), whereas bead tips are best for stringing material that knots well, and might get cut or frayed if crimped. Bead tips aesthetically hide the secure hold created by the knot underneath them.
