Review on Shinwa Stainless Machinist Engineer Graduations Test, Measure & Inspect in Dimensional Measurement by Billy Berry

This is a strong and sturdy ruler. It is very clearly marked in inches on one side and metric on the other. The inch side is marked 32 on one edge and 64 on the opposite edge. The metric side has a 1mm mark on one edge and a 0.5mm mark on the other edge. This is my favorite style because it's less of a hassle when trying to get a specific reading. I have other rulers that seem to be of the same quality, but they usually print the same thing on both sides, making it difficult to get good measurements.
