notes: label: Description
content: This is a patent model (US29963A) for the improvement of wood screws, patented by George Freeman of New York on September 11, 1860. This patent is for an improved wood screw that has built-in cutters on its head. Its basic use is to let the screw cut a countersink in the wood as it’s driven in, so the screw head sits flush with or slightly below the surface, eliminating the need for a separate countersinking tool.
