After studying with Tage Frid, Cosman took the technique he learned and kept practicing cutting half-blind dovetails. Eventually, he developed a tool to make it simpler – the Kerf X-10.
To use, make your first cut to the side of the half-blind dovetail. Place the Kerf X-10 into the kerf of the cut you just made. Strike the Kerf X-10 with a mallet to drive it down into the material that is left in the corner of the cut, making sure that you stop at your marked depth line. Be sure to take several small passes, rather than one large one. The Kerf X-10 will shave off that portion, leaving you with a clean side. Repeat on the other side of the dovetail.
This handy blade is sharpened square to the sides and ready to use right out of the box. Being slightly larger than the standard kerf of most dovetail saws allows the Kerf X-10 to shear off the sides of the cut, leaving a clean, smooth joint side.
Built for years of use, the sturdy brass back is attached to the handle with a copper pin-secured tenon and epoxy. Similarly, the blade is attached to the brass back with peened copper pins.
