Review on 📐 Acurit Precision Measuring Drafting Drawing Tool by Josh Endricko

You could spend a lot more but I'm not sure you can get much better. It works well (doesn't slip), the graduations are easy to read, and it looks pretty solid. I like using it. If you've used a rotating ruler before, take some time to practice as there's a slight learning curve. For example where to press and how hard, and maybe make a very light line the first time to check your accuracy (rectangle).
