Sharpening Process:
- Power On: Turn on the sharpener using the power switch located on the front. The motor will start.
- Stage 1 (Coarse Sharpening):
- Insert the heel of the knife blade into the left slot of Stage 1.
- Pull the knife slowly and steadily towards you, applying light downward pressure. The precision guides will hold the blade at the correct angle.
- Repeat this motion 3-5 times for each side of the blade (alternating between the left and right slots of Stage 1).
- For very dull or damaged knives, more passes may be required.
- Stage 2 (Fine Sharpening/Polishing):
- Once Stage 1 is complete, move to Stage 2. Insert the heel of the knife blade into the left slot of Stage 2.
- Pull the knife slowly and steadily towards you, applying very light downward pressure.
- Repeat this motion 3-5 times for each side of the blade (alternating between the left and right slots of Stage 2).
- This stage hones and polishes the blade, creating a razor-sharp, burr-free edge.
- Check Sharpness: Carefully test the sharpness of the knife. If not sufficiently sharp, repeat Stage 2.
- Clean Knife: After sharpening, always wipe the knife blade clean with a damp cloth to remove any metal particles before use.
- Power Off: Turn off the sharpener and unplug it from the outlet when finished.
