I figured maybe salvage was the right choice. I caught a show the other day and due to my horrible memory Im cant remember what was used.

He was dismantling pallets and using some sort of Air Tool to knock the nails in one hit back into the stringer of the pallet. What was that tool used? I have a simple air gun but it doesnt do the trick. I have a lot of extra pallets that Id like to use for the wood, was thinking of easier less back breaking ways of going about it.
