Step-by-Step Guide on How to Sharpen Ninja Blender Blades

Once you have all your tools and materials at hand, you will have to disconnect the blender from the power outlet. This is important as it will protect you from the danger of getting electrocuted or injured in case the blender is turned on accidentally.

With that being said, below is the step-by-step guide on how to sharpen your blender blades at home –

1. Dismantle the Blender Jug from Its Base

Dismantle the Blender Jug from Its Base

Hold the blender jug and separate its base from the top. Once you have the base removed, clean the blades thoroughly with soap and a brush. For stubborn debris, brush a little harder until it gets off.

2. Remove the Blade from the Base

Remove the Blade from the Base

To remove the blade, you will have to twist it counter-clockwise. Without too much force, it should come off in your hand. Be careful when handling the blades, and avoid touching them directly as you could cut your fingers. If available, use protective gloves or a kitchen mitt to hold the blade.

After twisting out the blade, you should see a gasket-like protective ring or seal. Keep it aside, don't lose it.

3. Use Sharpening Stone/Combined Diamond Sharpener to Sharpen the Blade

Use Sharpening Stone

If the blade hasn't dried completely, wipe it with a tissue or a towel. You can use one or both tools, but a combined diamond sharpener makes the process less tedious. Here's how to use them –

a. Sharpening Stone

Some blenders have two blades while others have four blades, two facing upwards and two facing downwards. You will have to run the edges of the blades facing upwards at a slight angle on the sharpening stone. This has to be repeated for each side of all the blades until they are sharp enough.

As a safety precaution, keep the sharp side of the blade facing away from you, i.e., in the opposite direction, to prevent accidental injuries.

b. Combined Diamond Sharpener

A combined diamond sharpener has different stages of sharpening blades. Each stage has two or more slots, but only the first slot of the first and last stage is needed to sharpen single-edged blades. For double-edged blades, the stages vary depending on the blade’s thickness.

The first and second stages involve sharpening the blades, while the third stage is for smoothening the blades' finish. All sides of the blades have to be sharpened on both edges for double-edged blades, or on the sharp edges of single-edged blades.

It is a simple process once you place the blade in its appropriate slot. You just have to slide each of the blades back and forth in the slots until you feel like the blades have sharpened enough. Keep in mind, however, to not check the blades’ sharpness with your fingers.

4. Reassemble All Components of the Blender

Reassemble All Components of the Blender

Before putting it all back together, wash the jug thoroughly with soap and water. Once you're sure that there is no residue left, it's time to get to the final step.

Wash the blade once more and wipe it dry with a towel or tissue. Place the protective seal followed by the blade on the base of the blender jug.

After the blade is fixed, attach the base to the blender jug, and you should be done!

But how can you tell if the blades are sharp enough or need more sharpening? Refrain from using your finger to check the sharpness at all costs! Instead, you can test the blades on a piece of paper or anything that can be cut. Moreover, sharpened blades should have some glint at the edges, making them look sharper than before.

If you still cannot tell the difference, the best way to make sure is by assembling everything and using the blender to blend food.
