Figure 4.2: Detailed diagram illustrating the three sharpening stages (1, 2, 3) and the overall dimensions of the sharpener. Stage 1 is for coarse sharpening, Stage 2 for fine honing, and Stage 3 for ceramic refining and serrated knives.

• Stage 1 (Coarse): Equipped with a 325 grit (45 micron) electric-powered diamond wheel. This stage is for setting the initial edge on very dull or damaged straight-edge blades.
• Stage 2 (Fine): Features a 1000 grit (15 micron) electric-powered diamond wheel. This stage hones and refines the edge, preparing it for the final polishing.
• Stage 3 (Ceramic): A manual V-slot with ceramic abrasives. This stage is used for quick touch-ups, polishing the edge, and is the only stage suitable for sharpening serrated knives.
• Removable Magnetic Receptacles: Located at the bottom of the sharpener, these receptacles collect metal filings for easy cleanup.

2. Connect the AC to DC 12V power adapter to the sharpener's power input port.
3. Plug the power adapter into a standard electrical outlet.
4. Flip the power switch to the 'ON' position. The indicator light will illuminate, and the sharpening wheels will begin to rotate quietly.

6. Operating Instructions

General Sharpening Tips:

• Always clean your knife blade thoroughly before sharpening.
• Apply light, consistent downward pressure on the blade as you pull it through the slot. Do not press too hard.
• Pull the knife slowly and steadily from the heel to the tip through the sharpening slot. Maintain a consistent speed.
• The sharpener is designed with pre-set sharpening angles (20 degrees) for optimal results. You do not need to adjust the angle.
• For double-bevel knives, the sharpener simultaneously sharpens both sides of the edge, saving time and ensuring even sharpening.

Sharpening Straight-Edge Knives:

For best results, follow the 3-stage process:

1. Stage 1 (Coarse Sharpening):
   • Use this stage for very dull, damaged, or newly acquired knives.
   • Insert the heel of the knife blade into the left slot of Stage 1.
   • Pull the knife slowly and steadily towards you, from heel to tip, maintaining light downward pressure.
   • Repeat this process 5-10 times, or until a burr (a slight ridge of metal) forms along the edge.
2. Stage 2 (Fine Honing):
   • Move to Stage 2 for honing and refining the edge created in Stage 1.
   • Insert the heel of the knife blade into the left slot of Stage 2.
   • Pull the knife slowly and steadily towards you, from heel to tip, maintaining light downward pressure.
   • Repeat this process 5-10 times. This will remove the burr and further sharpen the blade.
3. Stage 3 (Ceramic Polishing):
   • This stage is for final polishing and quick touch-ups.
   • Insert the heel of the knife blade into the left slot of Stage 3.
   • Pull the knife slowly and steadily towards you, from heel to tip, maintaining light downward pressure.
   • Repeat this process 3-5 times.

Sharpening Serrated Knives:

Only use Stage 3 for serrated knives. Using Stages 1 or 2 on serrated blades can damage the sharpener and the knife.

1. Insert the heel of the serrated knife blade into the left slot of Stage 3.
2. Pull the knife slowly and steadily towards you, from heel to tip, maintaining light downward pressure.
3. Repeat this process 5-10 times, focusing on sharpening each individual serration.

After Sharpening:

• Carefully wipe the sharpened blade with a damp cloth to remove any metal filings.
• Test the sharpness of your knife on a piece of paper or a tomato. A properly sharpened knife should slice cleanly without tearing.

Cleaning the Sharpener:

The SHARPAL 198H is designed with removable magnetic receptacles to collect metal filings, making cleanup easy.

2. Locate the magnetic receptacles on the underside of the sharpener.
3. Carefully slide out the receptacles.
4. Empty any collected metal filings into a waste bin.
5. Wipe the receptacles clean with a dry cloth.
6. Slide the receptacles back into their slots until they click into place.
