Purpose
When the teeth of a saw are formed from the body, they are in line and the same thickness as the blade immediately behind them. A saw with this configuration is described as having 'no' or '0' set.
To prevent the body of the blade binding and for other enhancements to the cutting action, the teeth can be set (angled out) from the blade. Teeth can be set in several patterns: single-sided set, alternating set or a patterned set. Most Western and Asian handsaws use an alternating set, whereby a tooth is set the opposite direction from the preceding one. Specialized tools like veneer saws or flush-cut saws may be set only to one side. Some hacksaws and machine saw blades have patterned sets that may require specially designed saw sets to create.
See Saw and Sawfiler for more detailed information about set, kerf, and maintenance of saws.
A saw set makes the process of setting the teeth easier, more consistent or both.

Famous quotes containing the word purpose:
“Rule of criticism: only attend to the shape, and the purpose will manifest itself.”
—Mason Cooley (b. 1927)
“Man, her last work, who seemed so fair,
Such splendid purpose in his eyes,
Who rolled the psalm to wintry skies,
Who built him fanes of fruitless prayer,
Who trusted God was love indeed
And love Creation’s final law—
Though Nature, red in tooth and claw
With ravine, shrieked against his creed—”
—Alfred Tennyson (1809–1892)
“Nowadays, if New York has a heart, it might be the Garden. Almost everyone goes there, for one purpose or another. There are dog shows, and Sonja Henie and mass meetings.”
