Setting the Honing Angle:

The distance the blade projects from the front edge of the Honing Guide determines the honing angle. The following list gives approximate distances in 5 degree increments:

  • 20 degrees: 2-1/16" (52.38mm)
  • 25 degrees: 1-1/2" (38.10mm)
  • 30 degrees: 1-5/32" (29.36mm)
  • 35 degrees: 7/8" (22.22mm)
  • 40 degrees: 5/8" (15.87mm)
  • 45 degrees: 7/16" (11.11mm)
  • 50 degrees: 5/16" (7.93mm)

Using the Mortise Chisel Jaw Pair increases the honing angle approximately 5 degrees. For example, setting a blade in the Mortise Chisel Jaw Pair at 1-5/32" for 30 degrees, will result in an angle closer to 35 degrees.

To Attach Jaws:

To ensure the jaws are attached squarely in the guide, set the jaws onto the body of the guide without tightening the lock screws, then close the guide with the thumbscrew. Once the guide is closed and the two jaw halves are making contact, tighten down the lock screws. The jaws should now be properly aligned in the tool.

Deneb Puchalski's Angle Setting Jig PDF is a great tool for setting the correct projection of blades and chisels in a honing guide. The Angle Setting Jig PDF offers plans and material suggestions so you can assemble your own.
