Our Marking Gauges (Kebiki Dai) are used to layout straight lines parallel to the edge of your work. They provide a far more precise, accurate line on stock than does a pencil. Unlike Western marking gauges, the cutters of Kebiki are sharpened with only a single bevel. This give a very clean line without any tearing of the grain. The blades are made from high carbon tool steel and the bodies from best quality Japanese White Oak or Japanese Red Oak. This Kebiki is used for scoring lines parallel to a straight edge. It is also quite useful for layout work of many types of joints, including dovetail and box joints.
