Longzon ZForge V2

No, this sharpener is specifically engineered for straight-edged kitchen knives. Using it on serrated blades or scissors will damage both the tool and the sharpener's grinding discs.

Most Western-style kitchen knives perform best at a 20-degree angle, while thinner Japanese-style blades often require a steeper 15-degree angle. If you are unsure, check your knife manufacturer's specifications, as using the wrong angle can prematurely wear down the blade or fail to create a sharp edge.

The ZForge V2 is designed for efficiency, so a full charge provides ample power to sharpen a complete set of kitchen knives in one go. We recommend keeping it charged between uses to ensure consistent motor speed, which is critical for an even grind.

The four stages allow you to customize the process based on the condition of your blade. You start with the coarse diamond discs (360# and 600#) to repair chips or reset a dull edge, then move to the fine oilstones (3000# and 6000#) to hone and polish the edge for a razor-sharp finish.

Maintenance is straightforward. Because the unit is not dishwasher safe, simply wipe the exterior with a damp cloth and use a soft brush to clear any metal filings from the grinding discs after each use. Avoid using water or liquid cleaners directly on the motor or internal components.
