Marking, mortise, and combination gauges come in myriad styles and prices. What differentiates them from one another is the number and type of cutters each employs. Marking gauges have a single cutter for scribing one line at a time. Mortise gauges have two cutters and are used mostly for marking parallel lines to establish the width of a mortise. Combination gauges typically have three cutters: a single cutter on one side of the beam for use as a marking gauge and an additional pair on the other side of the beam for laying out mortises.

This beech combination gauge from Marples has standard sliding adjustment and a plastic thumbscrew. It’s also available in rosewood and brass.
