About 15 years ago I built a house and bought a 16 ounce frame hammer. I didn't think I needed it until I started clogging my nails with my 12oz and then another guy suggested I give it a try. Those big nails went straight in. And after we finished the house, the hammer disappeared. Maybe there was drywall somewhere, or maybe someone took their tool and snatched my hammer. But he disappeared. This is a very, very useful tool when you need to hammer in some big nails. And it's a great hammer. The head and handle are made from one piece and look indestructible. But then something else was added, a small magnet, and a flat piece was also cut out. The idea, I think, is that you can stick a nail in, hammer it in once to secure it, and then hammer it in. It might work with a 16p nail, but it didn't work with the slightly smaller nail I tried. It is set at a slight angle so that the nail pops out when it hits the wood without being fixed. This is the first hammer I've ever had with this feature and I've never missed it before. Hammers have been around for a long time and have worked great over the years. Adding a cutout and magnet is not required. So I'm going to use this hammer without even trying to use a magnet to cut out the piece. He's already found a good spot to hang it on my tool wall until I need it.
