This is the step where we sharpen the blade using a sharpening stone. There are different types of sharpening stones available in the market. They are also known as whetstones. A good whetstone with 1000 to 1500 grit will be enough for sharpening the mandoline blade.

To start sharpening, first put the blade on a plane surface. Now take the whetstone and start rubbing the sharp edge of the blade with the stone. You can rub the blade from top to bottom in a linear motion. Otherwise, you can rub the whetstone in a rotating motion on the sharp edge of the blade.

Keep rubbing the whetstone for at least ten to fifteen minutes. This will sharpen the blade and make the sharp edge very smooth. To test the sharpness, you can take a paper and try to cut it. If the paper cuts in one go, then you can be sure that the blade has been sharpened well. If the paper does not cut well enough, then you should continue sharpening the blade for a few more minutes.

Step – 4:

After you have finished sharpening, take the blade and wash it in clean water. Then dry it off using a clean cloth or hairdryer. Now take the blade and reassemble the mandoline. Make sure the blade is screwed tightly with the mandoline. Now wash and dry your mandoline, and it will be ready to be used with a sharpened blade.
