These are striking hammers for stonemasonry. Technically it's a chisel but designed like a hammer for comfort and useability (not an actual word🤷) there aren't hardened like a hammer would be. They mushroom 🤔 I find these so much more convenient and quicker than a saw. Any real mason can relate to this. Plus a hell of a lot less dust. No noise either unless you call the sweet sound of a hammer hitting steel noise. Personally some think it's an aphrodisiac. Not me though ..........quiet. #stone
