I have a carbide file guide for sale. I recently purchased this. It is an extremely well made guide. HOWEVER, WHEN THE CARBIDE FACES WERE ATTACHED. TWO DIFFERENT THICKNESSES WERE USED. They are a FRACTION in difference. If someone has the ability to surface grind the carbide. They would have an excellent guide. Will accommodate a 2.75" wide blade. Asking $55 shipped. PM IF INTERESTED.
