Glen-Drake Toolworks - Marking Gauge (Wheel Style)
The Tite-Mark combination marking gauge features a micro-adjustable fence and is available in two lengths.
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.
The Tite-Mark wheel-style marking gauge has an easy-to-see cutter that sliced cleanly, regardless of the grain direction, and the cutting wheel can be honed easily without removing it from the tool. This was one of my favorites.
