Veritas Dual Marking Gauge

Unlike a single-cutter gauge, the Veritas dual marking gauge has two independently adjustable rods, letting you set two dimensions at once and switch between them without re-measuring.

Yes, both wheel cutters retract fully into the reference face, so you can extend just one and use the gauge as a standard single-cutter marking gauge.

Use the outside cutter for most traditional marking gauge work; switch to the inside cutter only when thicknessing a workpiece, since its bevel faces away from the reference face.

No, the shaft clamp is an optional accessory, available separately, that locks the relative position of both rods so you can repeat one mortise size at different offsets.

A hardened wheel cutter slices across wood fibers instead of tearing them the way a pencil or blunt scriber does, leaving a fine, precise line that registers a chisel accurately.
