For those that use an engineer's scale, this flat six inch ruler is very convenient, and easier to carry than the standard 12 inch triangular type scale. It is great for use in the office, on the road, at the job site, or in the field. The plastic material is pretty durable, and the etching won't fade unless subjected to heavy wear or physical damage. There are cheap versions where the lines and text quickly wear away. With care, the scale could easily last for years.
