How To Sharpen A Mandoline Slicer

Mandolines have been around for hundreds of years, and although they have evolved over time, their basic design remains the same. All mandoline slicers are equipped with a blade, and in most models, they also feature a main platform or surface.

The blade is an essential element when it comes to the functionality of a mandoline slicer. Although it’s important to keep your entire unit in good shape, having a sharp, debris-free blade will help extend its lifespan and increase its usability.

Safety Precautions

Before getting started, remember that a mandoline slicer can severely injure you if you are not careful. Take all the necessary safety precautions to prevent any accidents or injuries. This includes wearing gloves and any other security accessory that can prevent any issues.

Set Up Your Working Space

Secondly, you want to find a flat, stable surface where you can place all parts you remove from your mandoline, including the blade. Make sure the surface is even to prevent any sliding, thus causing possible leg injuries.

Read The Instructions Of Your Sharpening Stone

Assuming you have already reviewed the instructions of your mandoline slicer, you should carefully read the manual for your sharpening stone as well. Read through them a few times and get familiarized with your stone before proceeding.

Remove The Blade

Use the necessary tools to remove the mandoline blade and place it to one side. You can also take this opportunity to clean the rest of your appliance, focusing on those hard-to-reach places that are impossible to get when the blade is in.

Prepare The Sharpening Stone

On the flat surface you have chosen, set down your sharpening stone and make sure it’s stable and that it will not slide when in use.

Position The Blade At The Correct Angle

Remember that you have to get the right angle to effectively sharpen your blade, so try to position the blade correctly on the stone. Most of the time a 20° angle should do the trick, but double check the instructions manual for more detailed information on your specific stone.

Push The Blade Across The Sharpening Surface

After finding the right angle, you should slowly push your blade across the sharpening surface over and over again, verifying that the blade is getting sharper. This may take some practice, but be patient and give yourself time to work out all the minor details.
