Use for a neat finish on a strand of beads and to attach to a clasp. Tie a knot around a small bead, thread through tip and continue to string. Finish with bead tip and another knotted bead (making a knot big enough to not pull through the hole can be tricky with the smaller threads. Works with the silk though. Bend hook to attach to clasp. Sort of half of a clamshell tip.
