Pulling staples maybe?
Close. It's a nail puller. I have one. It works great if you don't mind damaging the board. You set the open jaw over the nail head. As you use the slide hammer handle to drive the jaw under the head it closes. Then you extend the handle and pry towards the foot.

You need a sacrificial board under the foot to keep from damaging the board attached, but usually, like when opening crates, it doesn't matter if the board is damaged or not...![]()


Also great blood blister generator on top of being a nail puller and wood destroyer.
