3. സജ്ജീകരണം
Follow these steps to assemble and set up your knife sharpener:
- അടിസ്ഥാനം സുരക്ഷിതമാക്കുക: Identify the G-clamp on the sharpener's base. Tightly clamp the base to a stable surface such as a table or kitchen counter. Ensure it is firmly secured to prevent movement during sharpening.
- Assemble the Rods: Insert the main vertical rod into the base. Attach the horizontal guide rod to the vertical rod, ensuring all screws are tightened to prevent wobble.
- Attach the Blade Fixture: The metal blade fixture is designed to hold the knife firmly. Ensure it is properly aligned and secured to the main assembly.
- Prepare the Sharpening Stone: Select the appropriate grit whetstone for your sharpening needs. For initial sharpening or repairing damaged edges, start with a lower grit (e.g., 120 or 320). For refining and polishing, use higher grits (e.g., 600 or 1500).
- Mount the Stone: Insert the selected sharpening stone into the stone holder on the guide rod. Ensure it is securely fastened.

4. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
4.1. Mounting the Knife
Carefully place the knife blade into the metal blade fixture. Ensure the blade is centered and held firmly. The fixture is designed to hold the blade securely without causing damage.
4.2. Adjusting the Sharpening Angle
The RX-009 allows for a wide range of sharpening angles, from 5 to 90 degrees. To adjust the angle, unscrew the knob on the vertical rod that controls the height of the horizontal guide rod. Move the guide rod up or down to achieve the desired angle. A lower angle (e.g., 15-20 degrees) is suitable for fine cutting edges, while a higher angle (e.g., 25-30 degrees) is better for more durable edges on utility knives. Tighten the knob once the desired angle is set.

4.3. മൂർച്ച കൂട്ടൽ പ്രക്രിയ
- Lubricate the Stone: If using whetstones, apply water or honing oil to the stone surface. Keep the stone wet throughout the sharpening process.
- Begin Sharpening: Hold the handle of the stone holder and gently slide the stone across the blade edge, moving from the heel to the tip of the knife. Apply consistent, moderate pressure.
- Flip the Blade (360° Rotation): The innovative 360° rotation flip design allows you to sharpen the other side of the blade without removing the knife from the clamp. Simply rotate the blade fixture to expose the opposite side. This ensures symmetry and consistency in the sharpening angle.
- Repeat and Progress: Continue sharpening each side until a burr forms along the entire edge. Once a burr is felt, switch to the next finer grit stone and repeat the process. Reduce pressure with finer grits.
- അന്തിമ പോളിഷ്: Finish with the 1500 grit stone for a highly refined and polished edge.

4.4. Versatile Sharpening
Beyond knives, this sharpener can also be used for other tools such as scissors, peelers, and small saws, provided they can be securely clamped in the fixture.

5. പരിപാലനം
- വൃത്തിയാക്കൽ: After each use, clean the sharpening stones by rinsing them with water to remove metal particles. Wipe down the metal components of the sharpener with a damp cloth to prevent rust and maintain cleanliness.
- ഉണക്കൽ: Ensure all components, especially the stainless steel parts and stones, are thoroughly dried before storage to prevent corrosion and mold growth on the stones.
- സംഭരണം: Store the sharpener and its components in the provided storage casing in a dry place, away from direct sunlight and extreme temperatures.
- കല്ല് പരിചരണം: Whetstones may develop grooves over time. Periodically flatten them using a lapping plate or coarse sandpaper on a flat surface to maintain optimal sharpening performance.
6. പ്രശ്നപരിഹാരം
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| Knife not getting sharp. | Incorrect sharpening angle; insufficient pressure; worn-out stone; not progressing through grits correctly. | Verify and adjust the sharpening angle. Apply consistent, moderate pressure. Ensure stones are clean and not excessively worn. Start with a coarser grit and gradually move to finer grits. |
| Sharpener wobbles during use. | Base not securely clamped; loose screws on assembly. | Ensure the G-clamp is tightened firmly to a stable surface. Check and tighten all assembly screws on the rods and fixtures. |
| Stones are not cutting effectively. | Stones are dry; clogged with metal particles; glazed surface. | Keep stones adequately lubricated with water or honing oil. Clean stones regularly. If glazed, flatten the stone surface. |
| Blade is scratched or damaged. | Improper blade mounting; excessive pressure; debris on stone. | Ensure the blade is securely and correctly mounted. Use appropriate pressure. Clean stones before and during use. |
