A simple 15cm metric ruler made from solid brass. Forged out of a brass plate with the force of 45 tons, bent, arranged, and laser engraved to create this basic and ubiquitous tool. Draw a straight line and measure to your specification. One side of the ruler is angled to make pick-up and drawing lines easy with fountain and water based pens.
Although it has golden gloss at the beginning of use, the brass will oxidize and a patina may appear, changing in appearance to that of an antique tool. And while patina is a form of rust that most appreciate, by using a metal polish, it is possible to restore the original shininess whenever you like.
15cm is 5.9". Again, this is a metric ruler in centimeters only.
