Rob Cosman Dovetail Marking Knife

Includes two extra blades (see photo). From Rob’s site: The knife body is made of cast metal and is surprisingly hefty. Two piece body with space to store a second blade. The rectangular handle will register in your hand to help you “feel” the blade's position. Comes with our .019" (19 Thousandths of an inch) Saw-Tooth Blade. Replacement blades available. Regular Saw-Tooth Blade: Designed specifically for use with my dovetail transfer technique. Made of the same material as our saw plates, with a .019 inch thick kerf. .019 Saw Tooth Blade has 22 TPI so it fits into the kerf easily. Allows you to "saw" a starting kerf in the pin-board.
