Rob Cosman’s Kerf X-10

Back in the summer of 1987 I had the great fortune of working with Tage Frid. Tage showed me his method of finishing the saw cuts on the pin board of a half blind dovetail. This joint only allows the dovetail saw to be used between the marking gauge lines, leaving half the cut to be carved with chisels. By using the Kerf X-10 as shown in the video, the saw cut is completed and the process of waste removal is sped up and done more accurately.
