The WoodRiver® Wheel Marking Gauge 7" finely honed replacement blade is the perfect accessory for the simple, yet effective WoodRiver® Wheel Marking Gauge. The gauge has a single bevel edge wheel that scribes a fine line without tearing the wood fibers and does not wander with the wood’s grain. A precision ground brass shoe glides against the edge of the workpiece, and the knurled brass knob makes adjustments quick and easy.
