TEARING RULER

摘要

A ruler (10) for craft applications has an efficient construction which employs a pair of tearing edges (24, 26) to facilitate tearing and a pair of measurement scales. The tearing ruler (10) may be angularly oriented to facilitate either tearing or measurement activities. The tearing edges are defined by various waveform patterns (26, 26B, 26C, 28A, 28B, 28C). The tearing edges may be interchangeable.
