These forged hammers are great for sinking, embossing, and planishing and many other tasks. They feature canted faces for a more ergonomic swing, to allow a more direct blow, and the ability to get into those hard to reach places. One face is flat, with contoured edges to avoid marring your piece with an off angle blow. While the other has a radius similar to the pad of your thumb. Not to mention, they are fitted on SC Studios signature handmade Osage handle!
