The Dual Diamond Knife sharpener is extremely simple to use: the suction cup with its vacuum system provides optimal stability on all smooth surfaces.
If you have previously avoided sharpening household or outdoor knives yourself, now is the time to think again: The DUAL DIAMOND makes it really easy. Even delicate commercial knives can be sharpened with high precision.
First, attach the vacuum suction cup foot on a smooth and stable surface. You now have both hands free and can run your knife along the grinding wheels.
The two wheels - one for coarse and one for fine grinding - are coated with diamond powder. First you draw them through the coarse side and then through the fine side. The grinding angle is fixed - so it can go wrong. It‘s that simple.
