The carpenter's brace is another instance of divergent design after a common origin. Refer again to Van Vliet's etching of the woodworker's shop (fig. 28), to the detail from Moxon (fig. 36), and from Roubo (fig. 37). All show the brace in a form familiar since the Middle Ages, a shape common to both delineators and craftsmen of the Continent and the British Isles. But, as the plane changed, so changed the brace. The standard form of this tool as it was used and produced in the United States in the 19th century can be seen in another plate from the catalogue of the Castle Hill Works at Sheffield (fig. 38). This English influence on American tool design is no surprise, since as early as 1634 William Wood in _New England's Prospect_ suggested that colonists take to the New World "All manner of Ironwares, as all manner of nailes for houses ... with Axes both broad and pitching ... All manners of Augers, piercing bits, Whip-saws, Two handed saws, Froes ..., rings for Bettle heads, and Iron-wedges." [Illustration: Figure 45.--19TH CENTURY: THE UPHOLSTERER'S HAMMER is an unknown; it is not dated, its maker is anonymous, as is its user. It is of American origin, yet of a style that might have been used in England or on the Continent. This lack of provenance need not detract from its significance as a material survival. This hammer, the brace (fig. 46), the bevel (fig. 47), and the compass saw (fig. 48) are sufficiently provocative in their design to conjure some image of a technology dependent upon the skilled hand of craftsmen working in wood and of the relationship between the hand, the tool, and the finished product.

This aspect of variety of detail--sophistication, crudeness, decorative qualities or the like--reflects something of the individuality of the toolmaker, a quality completely lost in the standardization of the carpenter's brace.
