Chris's Tips
The combination square was invented by Leroy Starrett (yes, that Starrett) in 1877. It's one of those basic tools that should be in every machinist's (and woodworker's) tool box.
We carry several Starrett 12" combination square sets. What's the difference? There are several features that affect the price. One is the protractor head. Squares with a reversible protractor head cost more. Another is the scale. Squares with satin chrome scales cost a little more.
