Key Features of the Manual Knife Sharpener:

The bottom of the sharpener features a high‐strength suction mechanism. When activated, the sharpener firmly attaches to smooth surfaces (countertops, tables) preventing movement during sharpening. This enhances safety, control, and sharpening accuracy.
- Manually Adjustable Sharpening Angle
The sharpening angle can be manually adjusted by turning the rotating top dial. Choose the ideal angle based on the knife type and blade thickness.
This feature allows professional‐level customization without complicated tools.
