W. B. Barnard & Son made quality scissors and squares, and although nice, they are not particularly plentiful. The company operated through the Civil War era. This pair of button hole scissors is marked with the patent date of Aug. 28, 1866. I've been unable to locate this patent, but it is also reported from a pair of Barnard wick trimming scissors. This tool is exceptionally well made with a steel frame that has shapely japanned handles. The clean blades have tightly fitting tool steel inserts for the edges, as well as a brass spanner washer for adjusting the blades. There is a brass screw stop that adjusts the length of the cut for cutting button holes. It is a very nice tool. Fine.
