We recently pulled up tile floors in our dining room to expose beautiful hardwoods underneath. The only problem is that about 1000 L-shaped nails are sticking into those hardwoods. Any tips for removal? We have tried the cat's paw tool, but it takes a very long time to remove each nail, and the tool doesn't always work. Also, we don't want to leave additional marks in the floor. Is there a better tool for this?
