If you're looking for a nice large soddie, you may give Eye-Brand a try. Their large one is almost 5 inches, good carbon steel and very rugged.
Also if they are still available, the Kissing Krane large brown mule. Take a little fine sandpaper and 0000 steel wool to the wood, and a little linseed oil rubbed in and buffed and you have a very nice traditional sodbuster.
