I'm not sure what value these have. They are basically nail pullers and they appear to be designed for nails used in nail guns. These nails have smaller heads than regular common nails. Well any way just throwing out the question since I feel that you really would want to be able to pry apart something with these small bars. This type of bar is really a nail puller and do to the configuration of the claw ends you'd have a hard time prying apart anything. Now if you had a hammer and needed to remove some nails well you'd be set.

Just an observation.
