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:
“It is my purpose to disclose the mystery at once, and to ask you to look for your interest,—should you choose to go on with my chronicle,—simply in the conduct of my persons, during this disclosure to others.”
—Anthony Trollope (1815–1882)
“With the breakdown of the traditional institutions which convey values, more of the burdens and responsibility for transmitting values fall upon parental shoulders, and it is getting harder all the time both to embody the virtues we hope to teach our children and to find for ourselves the ideals and values that will give our own lives purpose and direction.”
—Neil Kurshan (20th century)
“To me the sole hope of human salvation lies in teaching Man to regard himself as an experiment in the realization of God, to regard his hands as God’s hand, his brain as God’s brain, his purpose as God’s purpose. He must regard God as a helpless Longing, which longed him into existence by its desperate need for an executive organ.”
—George Bernard Shaw (1856–1950)
