- Lay the back onto the sharpening stone at a 90° angle to the long side of the stone
- Choose a fixed point on the neck up to which you want to sharpen
- Move the blade back and forth on the stone, applying light pressure and guiding it with your fingers
- Shiny areas indicate the even parts of the back, while the darker areas have not yet had contact with the sharpening stone (pay particular attention to the front section near the cutting edge, approx. 3 mm, and the edges)
- Pre-sharpen on the 1000 grit stone and finish on the 6000 grit stone until all scratches are removed
To ensure that a plane functions well, it is not sufficient to sharpen the blade alone. The chip-breaker also needs to be flat in order to guarantee a secure fit with no play and to prevent clogging with wood shavings.
When sharpening thick (Japanese) blades that have a large contact surface area, maintaining a constant angle is easier than with thin blades. One way to check how evenly pressure is being applied is to look at the tracks on the sharpening stone. A honing guide is very useful for helping maintain an exact bevel angle (e.g. No. 707168).
