My 300mm Starrett Combo Square is very accurate and versatile, but I also need something smaller. I have the 200mm version of this square. It matched snugly and proved to be my go-to square unless I needed the extra length (or versatility) of my combo square. However, in many cases it would be more convenient for me to have something even smaller, provided it is just as accurate. The 100mm variant is just the right thing. It's a perfectly square precision tool that's a joy to use. Now my transition to a square reminds me of how many times I've used a more unwieldy square than I really needed to. Actually, I couldn't get by with just a 100mm square, but ironically that's what I use most now. I recommend it to those who need a very accurate square.
