5. Operating Instructions

Before sharpening, ensure your knife blade is clean and dry. Always pull the knife towards you, never push it away from you, and apply gentle, consistent pressure.

5.1 Sharpening Japanese Knives (15° Angle)

1. Turn on the sharpener using the power switch.
2. Insert the heel of the knife blade into Phase 1 (15° diamond sharpening slot).
3. Pull the knife slowly and steadily towards you, maintaining light, even pressure, from the heel to the tip. The elastomer guide will help maintain the correct angle.
4. Repeat this process 3-5 times for each side of the blade, alternating between the left and right slots of Phase 1.
5. Move to Phase 3 (ceramic polishing slot). Insert the heel of the knife blade into Phase 3.
6. Pull the knife slowly and steadily towards you, applying very light pressure, from the heel to the tip.
7. Repeat this process 3-5 times for each side of the blade, alternating between the left and right slots of Phase 3, to achieve a fine, polished edge.
8. Turn off the sharpener and carefully wipe the blade clean with a damp cloth.

5.2 Sharpening European/Household Knives (20° Angle)

1. Turn on the sharpener using the power switch.
2. Insert the heel of the knife blade into Phase 2 (20° diamond sharpening slot).
3. Pull the knife slowly and steadily towards you, maintaining light, even pressure, from the heel to the tip.
4. Repeat this process 3-5 times for each side of the blade, alternating between the left and right slots of Phase 2.
5. Move to Phase 3 (ceramic polishing slot). Insert the heel of the knife blade into Phase 3.
6. Pull the knife slowly and steadily towards you, applying very light pressure, from the heel to the tip.
