Review on Starrett C636 300 Millimeter Graduations Thickness by Edwin Kreps

Excellent steel ruler. Well finished with clear markings. As other reviewers have pointed out, one side of each tier is marked in millimeters and the other in inches. Its dimensions are 0.5mm and 1/64 inch. The old-style Starrett typeface is very legible, as is the branding. The finish of the rule is excellent. It is a very accurate and handy measuring device.
