Hand saws have been around for thousands of years. Egyptian hieroglyphics exist depicting ancient woodworkers sawing boards into pieces. Ancient

saw blades, particularly if the wood was not 'smoothed up' by some method. As for preservation of hand saws, twenty-four saws from eighteenth-century England are known to survive.[1]

Materials for saw blades have varied over the ages. There were probably bronze saws in the time before steel making technology became extensively known and industrialized within the past thousand years or so.

The most popular material for handles of hand saws is applewood; in the early 1900s 2,000,000 board feet of applewood were used annually for this purpose.[2]

Sometimes cultures developed two main types of saw teeth: the

Rip saws, on the other hand, are usually shaped so that they form a series of tiny chisel-like
edges. The wood cells are contacted by the chisel and 'ripped' apart from the bundle of other cells. It is common that people do not recognize the difference and use saws both ways. However, a rip saw is much faster than a cross-cut saw when cutting with the grain but leaves a very rough cut, often with splinters on the surface, and has more difficulty maintaining a straight cut when cutting across the grain. The cross-cut saw can cut in any direction but is much slower than needs be when cutting with the grain.

The development of saws was also affected by several factors. The first was the importance of wood to a society, the development of steel and other saw-making technologies and the type of power available. These factors were, in turn, influenced by the environment, such as the types of ores available, the types of trees nearby and the types of wood which was in those trees. Finally, the types of jobs the saws were to perform was also important in the development of the technology.

Among

Basques and Australians, traditional hand sawing has generated rural sports. The Basque variant is called tronral
