198H Electric Knife Sharpener with Diamond Wheels

SHARPAL 198H sharpens double-beveled knife edges at approximately 20° per side.

No. The grinding wheels are not user-replaceable. Do not disassemble the sharpener, as disassembly may damage the product and void the warranty.

Durability depends on the hardness of the knives being sharpened, sharpening frequency, and usage habits. The abrasive wheels are designed for long-lasting household use.

The SHARPAL 198H is designed for most double-beveled straight-edge kitchen knives, chef’s knives, pocket knives, and outdoor knives.

The 198H is not recommended for scissors, single-bevel knives, ceramic knives, axes, pruners, mower blades, or other tools that require a different sharpening method.

Stage 1 uses a 325 grit coarse diamond wheel for quick edge setting and dull edge repair. Stage 2 uses a 1000 grit extra-fine diamond wheel for honing and refining the edge. Stage 3 uses a manual ceramic V-slot for final refining, burr removal, and quick touch-ups.

For a very dull knife, start with Stage 1, then move to Stage 2 and finish with Stage 3. For regular maintenance, Stage 2 or Stage 3 may be enough. Avoid using Stage 1 unnecessarily, as the coarse diamond wheel removes material faster.

For a dull knife, start with about 15 smooth pulls. Very dull edges may need around 20 pulls. For regular touch-ups, about 5 pulls may be enough. Harder steel blades may require more pulls than softer steel blades.

No. Use light, even pressure and pull the knife smoothly through the slot. Pressing too hard can reduce control, remove too much metal, or cause the wheel to slow down.

The 198H can be used for light touch-ups on some serrated knives with the manual ceramic Stage 3. Do not use the electric diamond wheels on serrated edges. Deep or specialized serrations are better sharpened with a tapered rod-style sharpener.

Some knives have a thick bolster or handle design that prevents the electric wheel from reaching the entire heel area. This is normal for many electric sharpeners. A manual sharpener or sharpening stone may be used for areas that are difficult to reach.
