Looking for a recommendation on which speed square to buy that I can keep in my tool bag. My neighbor has helped me with several projects and he is constantly pulling it out to help with making cuts and it seems like our powerful tool. I’m a little lost on what features will matter for occasional use. For example the Milwaukee and Klein speed squares have a slot for cutting pipe which I don’t think I’ll ever do. The Johnny Mach1 seems interesting since it has a built-in level, but it’s also twice the cost of all the other squares. What have you all found useful and valuable in choosing a speed square? #diy source
