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:
“A material resurrection seems strange and even absurd except for purposes of punishment, and all punishment which is to revenge rather than correct must be morally wrong, and when the World is at an end, what moral or warning purpose can eternal tortures answer?”
—George Gordon Noel Byron (17881824)
“I dont think life is absurd. I think we are all here for a huge purpose. I think we shrink from the immensity of the purpose we are here for.”
—Norman Mailer (b. 1923)
“For the purpose of knowledge, one must know how to use that inner current that draws us to a thing, and then the one that, after a time, draws us away from it.”
—Friedrich Nietzsche (18441900)
