6. What I Check for Ease of Use
I like tools that save me time, so I always consider how easy the speed square is to use. I prefer one with a comfortable size, easy-to-read markings, and a shape that lets me mark lines quickly. If I can hold it firmly and line it up without struggling, I know it will be a practical choice for my work.
