Review on Stainless Steel Woodworking Construction Protractor by Avanson by Jesse Stewart

Photo in packaging with beverage can to scale. Used in physics class for students to measure tilt angles. They had no trouble understanding how to use it, and it's more accurate than a protractor. The hold function is also useful. I'm sure it's more for woodworking than physics classes, but it should be great for that too. I like that the "weapons" are metal and marked in normal metric units used by sane people and also in evil units used by the barbarians, the English. Fractions are also marked in English units, which is very convenient.
