Review on 📐 Starrett 13C 6-Inch Double Square - Optimized with Hardened Blade by Sam Doucette

My caveat is the design of this square. The thing is, when you set the slider to a size roughly halfway down the calibrated ruler, and then move the square to transfer the measurement, you sometimes forget which edge of the ruler is the reference edge. If you have a combination square of the same design, you'll always know which side was the original edge since one side is 45 and the other is 90. I didn't think that through when I bought the quad and now I prefer my (unfortunately less well made) combo quads to this one. Just something to consider if you are unfamiliar with the daily use of this tool.
