Very handy tool for all sorts of projects

Square tools are great for all sorts of building products were you need to make perfect 90 degree angles. But they are also great for determining all sorts of angles between 0 and 90 degrees. In addition, this can be used as a straight edge, or a saw guide. I have not used it as a saw guide yet, but it does make for a good straight edge, though it is a little thicker than a ruler. The book that comes with this is a nice little guide any beginner handyperson should have.

Swanson Tool Company's square is the best one made

Swanson Tool Company’s speed square is absolutely the best. It’s not the cheapest, but it’s sturdy and well-made. The angles are 100% right on and the markings are clear and easy-to-read. Don’t buy the version without the black paint on the markings; the black paint makes the markings stand out. I have a couple of other generic speed squares that are far inferior from a store that starts with Harbor and ends with Freight and they are junk compared to this Swanson speed square. Spend the extra few dollars to buy this Swanson version of the speed square and you won’t regret it. I highly recommend this tool!
