After wrapping the neck of a wrapped loop neatly, one wrap tightly against the last, it's important to tuck in the end of the wire as close to the straight wire as possible. Otherwise, the piece may snag on a garment or irritate some skin. I use my crimp pliers to help alleviate the issue.

Using the flush cutters, I cut the wrap wire as short as possible.

Then I use the rounded space near the tip of the crimp pliers to squeeze the wire end down. Since the wire is going in a circle, this rounded shape is just right.

Squeezing the end of the wire snugly with the crimping pliers ensures the end is smoothly against the neck of the wrapped loop.
