The Starrett double square is the most accurate I have ever used. It has an easy to adjust screw, excellent rule that is both easy to read as well as precise. It is perfectly straight and square. I have been using it for all my projects from tenon layout, to finish cuts on small stock.
Its great holding a quality, heavy, accurate and not a flimsy tool
Worth Every Penny
I used the Starrett Double Square to lay out shoulders on hand cut Dovetail joints (pins and tails). It's quick, easy and dead on square. It's can also be used as a quick and easy thickness gauge.
Accurate and easy to use.
