straight edges

Lines without curves

Straight edges are tools with a precisely flat surface used for checking straightness, drawing lines, or guiding cuts.

They differ from rulers in that they may lack measurement markings—their purpose is the true edge itself.

The term also pluralizes the noun use of straight edge, referring to people who abstain from alcohol, drugs, and sometimes casual sex, often associated with hardcore punk culture: The show attracted a lot of straight edges.
