Supplies you need to sharpen Nutribullet blades

To sharpen your Nutribullet blades like a pro, you’ll need to gather a few things:

Supplies you need to sharpen Nutribullet blades

Sharpening stone

The most important item is a sharpening stone. You take a medium grit stone, around 600 to 800 grit. I noticed it provided enough abrasiveness to sharpen the blades without damaging them.

Lubricating oil

Using a lubricating honing oil helps the sharpening stone slide more smoothly over the blade. A light mineral, or jojoba oil, works well for this. Apply a few drops to the stone before sharpening the blade.

Paper towels

Keep some paper towels handy to wipe the blade and stone while sharpening.

Eye protection (optional)

It is a good idea to wear a pair of protective glasses, such as safety glasses, when sharpening the blade. I suggest this because sharpening can blow small metal particles into the air. And you don’t want them to fall into your eyes!

With these basic supplies and some patience, you’ll be sharpening your Nutribullet blades in no time. And I forgot to say yes. “Be sure to work slowly and sharpen the blades evenly.”

Step-by-step instructions for Sharpening Blades

Below, I’m sharing two methods for sharpening your blades. 

Disassemble and clean

Use the blade removal tool to unscrew the blade assembly from the Nutribullet cup. Gently pry the base of the blade from the cup using a flathead screwdriver. Remove the seal ring from the blade.

Wash all parts with warm, soapy water to remove built-up residue. Rinse thoroughly and dry. Especially clean the blade. But if you can’t clean the blade, I have a detailed post on this topic here: “How to Clean Nutribullet Blender Blade?”

Sharpen the Blades

Holding the blade assembly by the stem in one hand, slide the blades back and forth over the whetstone at a 45-degree angle using even pressure. Do 10 to 15 passes on both sides of each blade. Alternatively, you can use an electric blade sharpener. Carefully slide the blade assembly through the sharpener using light, even pressure. Repeat on both sides.

Then, wipe away any metal filings with a clean cloth. Rinse the blades again if needed.

How To Sharpen The Nutribullet Blender Blade with an Electric Knife Sharpener

Sharpening your Nutribullet blender blades with an electric knife sharpener is easy. First, put on safety gloves and unplug your Nutribullet. Take off the blade assembly and clean any debris. Set up the electric knife sharpener according to the instructions, adjusting the angle to around 20 degrees. Run each side of the blade through the sharpener, repeating until you’re satisfied with the sharpness. Wipe the blades clean, reassemble the Nutribullet, and test it with a small amount of water or a soft ingredient. This quick maintenance routine keeps your Nutribullet in top shape for smooth blending.
