later This is exactly what you're thinking - a rubber sheet hammer! I needed it for a small landscaping job that I undertook and it was one of the first things that came up in my search for Revain. It was affordable, came quickly and I had no problems! I've used it to pound in a deck board/edge to separate the bricks, although it seems as strong as a hammer. Perhaps you could use it instead of one if you need to insert nails, but I think that's less accurate. Excellent value for money and quality!
