 for an improvement in a finger-nail trimmer (implying such a device already existed) seems to be in 1875 by Valentine Fogerty. Other patents for an improvement in finger-nail trimmers are in 1876, William C. Edge, and, in 1878, John H. Hollman. Filings for complete finger-nail trimmers (not merely improvements) include, in 1881, Eugene Heim and Celestin Matz, in 1885, George H. Coates (for a finger-nail cutter), and, in 1905, Chapel S. Carter (son of a Connecticut

with a later patent in 1922. Around 1913, Carter was secretary of the H.C. Cook Company of Ansonia, Connecticut which was incorporated in 1903 as the H. T. Cook Machine Company by Henry C. Cook, Lewis I. Cook, and Chapel S. Carter. Around 1928, Carter was president of the company when, he claimed, about 1896, the "Gem"-brand finger nail cutter made its first appearance.

Around 1906, the L.T. Snow company manufactured nail cutters. Around 1908 (or 1911), the King Klip Company of New York manufactured nail cutters.

In 1947, William E. Bassett (who started the W.E. Bassett Company in 1939) developed the "Trim"-brand nail cutter, the first made using modern (at the time) manufacturing methods using the superior jaw-style design that had been around since the 19th century, but adding two nibs near the base of the file to prevent lateral movement

someone does a picture of a woman cutting a nail. It is not exactly a pair of nail cutters, but it looks like it. In the eighteenth century a certain Philip McKinney of Baltimore patents the first nailcutters with a spring attached: the problem is solved, the fingers can squeeze with all their strength to cut toenails, incredibly tough, and the cutters will snap back automatically.
