Is this the one? My wife got me one a few weeks ago and it is brilliant! https://www.screwfix.com/p/roughneck-pallet-buster-demolition-bar-1100mm/6765x?_requestid=539198 Lifts the boards in a controlled, easy manner and certainly cuts down on the back breaking tedium of crowbar work. I had it in the back of my car when I went past a building site last week. Turned the car around and after a short conversation with the gaffer I was able to strip 4 pallets measuring 4' x 4' in just over half an hour. Pallets were close boarded 4" planks and once the first one was off this exposed the runners and made the rest very easy to remove. Ended up with 57 boards as it enabled me to remove the under runners between the blocks as well, though 3 of these were damaged beyond use.
