Using a wire guardian is a great idea if you want to reinforce the ends on a necklace or a bracelet. They are available in different finishes and will add a neat and professional look to your pieces.
Take your flexible wire such as Beadalon, Accu-Flex or Soft Flex and feed it through a crimping bead. (Shown here with a crimp tube)
Next, feed the wire through one side of the guardian.
Then feed it through the other side.
Feed a clasp through the wire.
Position your clasp right to the very end.
Then slide the crimping bead up through both wires to the very end.
Holding the crimping bead close to the end squeeze the bead in the crimping station closest to the tip of the pliers.
Then use the crimping pliers to crimp the bead on the second station closest to the handle on the pliers.
Once you have added your beads trim off the excess and repeat the same process with an extension chain on the other end of your necklace or bracelet. To give your piece a polished look add a crimp cover once it is complete.
