If you use knives regularly, they may lose their sharpness. With sharpening stones you can ensure that you keep the sharpness of the knives and enjoy the ease of cutting for longer.

Made of a coarse and small grain, the sharpening stone contains two sides with different grain sizes. This means you don't have to invest in two sharpening stones.

Even sharper
Make your knives even sharper than with average knife sharpeners.

Avoid unnecessary loss
The different grain sizes prevent unnecessary loss of material during sharpening.

Optimal result
Weekly use of the sharpening stone ensures optimum cutting pleasure from your knives.

It's fun
Sharpening your knives yourself is just fun!

1. Place the sharpening stone in a layer of water and let it soak for between 10 and 15 minutes.
2. Place the sharpening stone with the coarse grain side up.
3. Hold the blade at an angle of about 10-15 degrees and move the blade back and forth across the grindstone. Do not put too much pressure on this. Repeat this until the desired sharpness is achieved.
4. Turn the sharpening stone over so that the fine grain size is facing up.
5. Move the knife back and forth over the sharpening stone to polish the knife nicely.
6. Clean the knife well, so that all sharpening residues disappear from the knife. Let the knife dry thoroughly before storing it to maintain its quality.
