My decking is attached with screw nails and I need to replace a large number of the boards. There are approx. 27 screws in each board and to use a cats paw and hammer is almost impossible. The boards are not next to each other so I can't remove one or two and then pry them up. Is there a tool available to speed up this process. Basically when I get the cats paw under the nail head I require a gorrilla to pull them out to point where I can get a bar underneath to fully extract them.
