History
Along with stone, mud, and animal parts, wood was certainly one of the first materials worked by primitive human beings. Indeed, the development of civilization was closely tied to the development of increasingly greater degrees of skill in working these materials.
Among early finds of wooden tools are the worked sticks from Kalambo Falls, Clacton-on-Sea and Lehringen. The spears from Schöningen (Germany) provide some of the first examples of wooden hunting gear. Flint tools were used for carving. Since neolithic times, carved wooden vessels are known, for example from the linearbandkeramic wells at Kückhofen and Eythra. Examples of Bronze Age wood-carving include trees worked into coffins from northern Germany and Denmark, and wooden folding-chairs. The site of Fellbach-Schmieden in Germany has provided fine examples of wooden animal statues from the Iron Age. Wooden idols from the La Tène period are known from a sanctuary at the source of the Seine in France.
Two ancient civilizations that used woodworking were the Egyptians and the Chinese. Woodworking is depicted in many ancient Egyptian drawings, and some ancient Egyptian furniture (such as chairs) has been preserved in tombs. The metal used by the Egyptians for woodworking tools was probably bronze or even copper, as ironworking was unknown until much later.
The progenitors of Chinese woodworking are considered to be Lu Ban (魯班) and his wife Lady Yun, from the Spring and Autumn Period. Lu Ban is said to have brought the plane, chalkline, and other tools to China. His teachings are supposedly left behind in the book Lu Ban Jing (魯班經, "Manuscript of Lu Ban"), although it was written some 1500 years after his death. This book is filled largely with descriptions of dimensions for use in building various items—such as flower pots, tables, altars, etc.—and also contains extensive instructions concerning Feng Shui, the ancient Chinese practice of geomancy. It mentions almost nothing of the intricate glueless and nailless joinery for which Chinese furniture was so famous.

- hollow grinding: a concave bevel on a chisel, gouge, or knife
- incannel: the concave surface of a gouge; a gouge sharpened on the concave surface
- interlocked grain: grain which has multiple longitudinal directions in alternating layers, typical of many tropical hardwoods, and very difficult to work and to produce smooth surfaces

- scorp: a drawknife with a curved, sometimes completely circular blade
- scraper: a flat blade with a burred edge used for smoothing

- softwood: wood from a gymnosperm tree, i.e. trees in the divisions Pinophyta and Ginkgophyta; not necessarily very soft or light wood, e.g. douglas-fir
- spalting: a fungal discoloration in wood where brown spots are outlined with fine black lines, often considered desirable
- split: to longitudinally separate wood along grain layers
- sweep: the curvature of a gouge, ranging from flat (little curvature, but not actually flat else it would be a chisel) to deep or quick

Topics in Woodworking
Woodworking is now a general term covering a wide range of skills and techniques.
- carpentry – Originally a carpenter was a wagon maker but carpentry has come to mean the general working of wood. Sometimes used to cover all aspects of woodworking, at other times carpentry refers to the least-skilled level of woodworking and larger projects, such as house building.
- joinery – The joining of two or more pieces of wood together, necessary in most woodworking projects. Also used particularly to refer to the joining of wood without the use of nails, screws, or other metal fasteners.
- cabinetry, cabinet making, cabinetmaker – The practice of utilizing many woodworking skills to create cabinets, shelving and furniture; a craftsman who specializes in the making of fine furniture. Implies a very high level of skill in woodworking.
- marquetry and parquetry – The practice of creating patterns by inlaying different wood veneers; with different colours and different grains complex patterns are formed. Originally used to decorate furniture, both are now often used to produce pictures. Often regarded as a fine art form, equal to sculpture and painting. Marquetry is distinguished from parquetry by the shapes used and formed - marquetry entails the creation of organic or scenic pictures, while parquetry involves geometric shapes.
- turning – The art of turning a piece of wood on a lathe and shaping it by holding various cutting tools against it.
- Wood species Choosing which type (species) of wood is correct for a given project.
- carving
- boat building – Professionally done by shipwrights.
- luthier & ndash; someone who builds or repairs stringed musical instruments such as guitars or violins.
- wheelwright – A maker of wooden wheels and spokes.
- cooper – A maker of casks and barrels.
- bodger – Now archaic, a wood-turner specializing making furniture and treen. Also a corruption of "botcher", a colloquial term for an incompetent workman.
Some of these refer to special techniques such as marquetry or turning, while others refer to a specialized product such as the cooper or wheelwright.
