Definition: A combination square is essentially a 12-inch ruler with a sliding handle that has two precision flat surfaces, one at 90-degrees and the other at 45-degrees to the ruler. This versatile woodworking tool allows the woodworker to easily scribe and mark lines on their woodworking projects or measure distances at these angles. The handle also contains a level vial for aligning the ruler plumb.
The handle may be slid to a position anywhere along the ruler and be locked in place with a set screw.
