text: Some men prefer to have a beetle made without any shoulder for the rings, but my experience teaches me that a beetle will wear longer, and the rings remain true longer, when it is made with shoulders than when it is made of a true taper without shoulders for the rings, because if a laborer happens to strike mostly on one side of the end of a beetle, unless the rings are so tight that they cannot be moved by much pounding, one side of the rings will be driven on farther than the other, and the faces will soon become one-sided, and then it will be an awkward tool to strike with.
