2. Components
Your HORL 2 sharpener consists of two primary components:
- Rolling Sharpener: This cylindrical unit contains two interchangeable sharpening discs. One side features a diamond grinding disc for initial sharpening, and the other side features a ceramic honing disc for refining the edge.
- Magnetic Angle Support: This wooden block has integrated magnets and two distinct sharpening angles: 15 degrees and 20 degrees. It securely holds the knife blade at the precise angle required for sharpening.

3. Setup
Before sharpening, ensure your workspace is clean and stable.
- Place the Magnetic Angle Support: Position the magnetic angle support on a flat, stable surface. Choose either the 15° or 20° side, depending on your desired sharpening angle (refer to the Operating Instructions section for guidance).
- Attach the Knife: Place your knife blade flat against the magnetic surface of the angle support. The magnets will hold the blade securely in place, ensuring the correct sharpening angle is maintained throughout the process.

4. Operating Instructions
Follow these steps to sharpen your knife effectively:
4.1. Choosing the Sharpening Angle
- 15° Angle (Fine Edge): Ideal for delicate cutting tasks, such as slicing sushi, sashimi, or for very hard steels with high carbon content. This angle creates a very sharp, finely honed edge.
- 20° Angle (Robust Edge): Recommended for most kitchen knives and general-purpose cutting tasks. This angle provides a durable, long-lasting edge suitable for everyday use.
4.2. Sharpening Process
- Initial Sharpening (Diamond Disc): With the knife securely attached to the magnetic angle support, use the diamond grinding disc of the rolling sharpener. Roll the sharpener along the entire length of the blade, applying light, consistent pressure. Perform approximately 3-5 passes per side, or more if the knife is very dull.
- Honing (Ceramic Disc): Flip the rolling sharpener to the ceramic honing disc. Repeat the rolling motion along the entire length of the blade, applying very light pressure. This step refines the edge and removes any burrs, resulting in a polished, razor-sharp finish. Perform 1-2 passes per side.
- Repeat for the Other Side: Detach the knife, flip it over, and re-attach it to the magnetic angle support on the same angle side. Repeat steps 1 and 2 for the other side of the blade.

5. Maintenance
Proper maintenance ensures the longevity and effectiveness of your HORL 2 sharpener.
- Cleaning the Discs: After each use, clean the diamond and ceramic discs to remove any metal particles. A simple pencil eraser can be used to gently rub off residual grinding dust from both discs.
- Storage: Store the sharpener in a dry place, away from excessive moisture or extreme temperatures.
- Magnetic Angle Support: Wipe the magnetic angle support with a dry cloth to keep it clean. Avoid submerging it in water.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knife not sharp enough | Insufficient passes on grinding disc; incorrect angle; worn discs. | Increase passes on the diamond disc; ensure correct angle is used; consider replacing discs if heavily worn. |
| Blade feels rough after sharpening | Insufficient honing; burr not fully removed. | Perform more passes with the ceramic honing disc, applying very light pressure. |
| Difficulty maintaining knife position | Magnetic angle support not stable; blade not fully seated. | Ensure the magnetic angle support is on a flat, non-slip surface. Press the knife firmly against the magnets. |
