A ruler made of stainless steel.
To care for a steel rule, keep it clean by wiping it with a soft, dry cloth after each use to remove dust and moisture that can cause rust. Store it in a protective case or a drawer to prevent bending or damage. Periodically, apply a light coat of oil to the blade to protect against corrosion, especially if you live in a humid environment. Avoid exposing the rule to extreme temperatures or harsh chemicals that could compromise its accuracy and finish.
I have steel rules that are marked down to 1/64 of an inch.
The steel rule is a measuring device. It is used to measure a piece of work such as engineering and is usually used just as if it were nothing more than a regular ruler.
A steel rule is most commonly refered to as an engineers rule.
"National Steel Rule's website has information on Steel Rule. Fine-Tools and Helmold may also have information on Steel Rule. Wikipedia has info on general rulers, too."

Accuracy, for a given size. The circular rule occupies space more efficiently and uses a spiral scale, so an 8 " Circular slide rule may be the equivalent in accuracy of 10 FEET of a linear rule.

A folding rule provides better accuracy and precision when measuring due to its stiffness, which helps maintain a straight and consistent measurement. In contrast, cloth or steel tapes are prone to bending or stretching, leading to less accurate measurements. The rigidity of a folding rule also enables it to be used for longer measurements without the need for additional support or reinforcement.
