Review on 📐 Shinwa Japanese Stainless Protractor: Accurate Degree Measurement Tool by Nico Ramdeen

I was a bit disappointed with the accuracy; When my surface plate is set to zero, the line width doesn't match the width. maybe 1/4 degree. Still pretty usable for most things, but still. You can see a thousand or three slops in a pole. The screw lock seems to work fine. The numbering is nice and bold and easy to read, but it's screen printed, not engraved on the metal, and they warn against using thinner as "thinner can remove scale". Time will tell how durable the scale is.
