### ⭐⭐⭐⭐⭐ Quality doesn't get any better than this.
*by S***. on April 11, 2026*

Its a Starrett... how could it get less than fives stars? Well maybe because its expensive but. You will only have to buy one of these your entire life and pass it on when you go. Im a steel fitter and this one of my most used tools. I have went through many cheap combo squares. I deal with a lot of torch cut plate that has slag and rust along the edges. It tears reg squares up and makes it hard for them to slide. It doesn't phase this one at all. Quality doesn't get any better than this.
