Stanley Bevel Edge Bench Chisels

  • the primary angle is set at 25 degrees using the stop block
  • the secondary angle is set at 30 degrees using the stop block [do not use the shim]

Notes:

  1. For day – to – day touch up sharpening only use the 8000 grit stone at the secondary 30 degree angle [do not use the shim]
  2. It takes a very long time (1 hour) to regrind the primary bevel on the 220 grit stone. Use the DMT Dia-flat lapping plate instead.
  3. Once the back is lapped, do not use any stone but the 8000 grit on the back.
  4. It takes a long time (30 minutes) to remove scratches from the 1000 grit stone. A mirror polish will appear after this work is completed. First the scratches will change to a cloudy or hazy appearance, then as more are removed the back will become mirrored.
