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 gives 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. The unique feature of this Kebiki is it can be used with either hand, and marking can be done on either side of the stock. It can be used to cut a single line or both blades can be used in tandem to lay out a mortise. Width of cut: 0-4˝.
