This is a pallet buster that was made from scrap materials on hand. The handle is a length of square tubing, the pivot a length of 1" pipe and the forks are 3/4" diameter "J" hooks (wall anchors) that came from a construction site (with permission), and were cut to length ( the threaded section removed).
In use, this tool breaks down pallets and skids, for reuse of the wood in projects or firewood. If you want to see similar tools in action, put Pallet Buster into Google, there are many videos out there demonstrating the action of it.
The finished project is shown in the last photo.
