TAILIEUCHUNG - WOODWORKING TOOLS

This history of woodworking hand tools from the 17th to the 20th century is one of a very gradual evolution of tools through generations of craftsmen. As a result, the sources of changes in design are almost impossible to ascertain. Published sources, moreover, have been concerned primarily with the object shaped by the tool rather than the tool itself. The resulting scarcity of information is somewhat compensated for by collections in museums and restorations. In this paper, the author spans three centuries in discussing the specialization, configuration, and change of woodworking tools in the United States.

As a result the sources of changes in design are almost impossible to ascertain. Published sources moreover have been concerned primarily with the object shaped by the tool rather than the tool itself. The resulting scarcity of information is somewhat compensated for by collections in museums and restorations. In this paper the author spans three centuries in discussing the specialization configuration and change of woodworking tools in the United States. The Author Peter C. Welsh is curator Growth of the United States in the Smithsonian Institution s Museum of History and Technology. In 1918 PROFESSOR . PETRIE concluded a brief article on History in Tools with a reminder that the history of this subject has yet to be studied and lamented the survival of so few precisely dated specimens. What Petrie found so discouraging in studying the implements of the ancient world has consistently plagued those concerned with tools of more recent vintage. Anonymity is the chief characteristic of hand tools of the last three centuries. The reasons are many first the tool is an object of daily use subjected while in service to hard wear and in some cases ultimate destruction second a tool s usefulness is apt to continue through many years and through the hands of several generations of craftsmen with the result that its origins become lost third the achievement of an implement of demonstrated proficiency dictated against radical and therefore easily datable changes in shape or style and fourth dated survivals needed to establish a range of firm control specimens for the better identification of unknowns particularly the wooden elements of tools handles moldings and plane bodies are frustratingly few in non-arid archaeological sites. When tracing the provenance of American tools there is the .
