How do you use a nail spacer?

A nail spacer tool is used to hammer nails without hitting your fingers. Here's how to use one:

1. Place the nail into the nail spacer tool.
2. Position the nail where you want to hammer it.
3. Hammer the nail until it's nearly all the way in.
4. Rotate the tool out of the way to remove it from the nail.
5. Finish hammering the nail completely into the surface.
