oto 56627.)] Change American hand tools in 1876 did not achieve the popular acclaim accorded the Corliss engine, yet few products shown by American exhibitors were more highly praised by foreign experts. It seems justified to suggest that American edge tools displayed at the Centennial had reached their high point of development--a metamorphosis that began with the medieval European tool forms, moved through a period of reliance on English precedents, and ended, in the last quarter of the 19th century, with the production of American hand tools "occupying an enviable position before the world."[11] [Illustration: Figure 54.--1809: THE INTRODUCTION of the gimlet-pointed auger followed Ezra L'Hommedieu's patent of 1809. From this date until its general disuse in the early 20th century, the conformation of the tool remained unchanged, although the quality of steel and the precision of the twist steadily improved.

(Original wash drawing, patent drawing submitted by R. Jennings, U.S. Patent Office, Record Group 241, the National Archives.)] The tool most highly praised at Philadelphia was the American felling axe (fig. 52) "made out of a solid piece of cast steel" with the eye "punched out of the solid." When compared to other forms, the American axe was "more easily worked," and its shape permitted an easier withdrawal after striking.[12] Sawmakers, too, were singled out for praise--in particular Disston & Sons (fig. 53) for "improvements in the form of the handles, and in the mode of fixing them to the saw." The Disston saw also embodied an improved blade shape which made it "lighter and more convenient by giving it a greater taper to the point." Sheffield saws, once supplied to most of the world, were not exhibited at Philadelphia, and the British expert lamented that our "monopoly remains with us no longer."[13] [Illustration: Figure 56.--1894: THE PERSISTENCE OF "JENNINGS" AS A TRADE NAME is suggested by the vignette from the "Illustrated Catalogue" of Baldwin, Robbins and Company, published in 1894.
