Review on 📏 16ME Multi Rule by General Tools by Trevor French

One of these rules was used with a protractor many years ago but lost. I bought this device mainly to check the tips of the drill bits when sharpening. That's what the fixed-angle part of the sensor is for. It should be 59 degrees. I tested it on a high end protractor and found it to be almost 2 degrees. Then I checked the protractor with an accurate 45 degree angle and the drawing protractor, it also deviates by 1-2 degrees. I seem to remember that my old one was still there.
