Review on 📐 Shinwa Japanese Stainless Protractor: Accurate Degree Measurement Tool by Sean Moran

This is a well made protractor that was built to survive in the toolbox. The main purpose of a protractor is to measure an angle. In my opinion this protractor is about 1/2 degree wrong and there is a video on You Tube showing how to fix it. Something else might make it better. Place a 6-inch ruler scale, a useful convenience, on the protractor's hand instead of leaving it empty, a waste of space. Also, extend the line along the angle scale from 0 degrees to 180 degrees, which will make it easier to align that axis.
