Cut once.

THE TOOL BEFORE THE TOOL
Tough Measuring Tools for Real Work.
Working rulers do what a flexible tape cannot: stay on the surface, hold a true edge, carry a fixed angle, and give the pencil or blade something physical to follow.

Measure
Read the working span in inch, metric, or both.
02
Mark
Carry one readable reference across the material.
03
Square
Transfer a fixed right angle from a working edge.
