How To Sharpen Ninja Blender Blades

How To Sharpen Ninja Blender Blades

Over the years, Ninja has formed quite a reputation for being one of the best blender brands in the industry, but not only does the brand know how to produce products that customers find appealing, but the brand also makes their products affordable. The company may be behind the likes of Vitamix and KitchenAid in terms of longevity and popularity, but the good things the brand is doing make catching up with the big guns easier than ever, with customers already rating the brand amongst the greatest in the market. Almost everyone who loves blenders thinks highly of Ninja, and that’s to show how far the brand has come.

If you’re familiar with the blender market, you’ll realize that Ninja, unlike many other top brands, manufactures high-quality products that can be purchased for lesser fees when compared to how other big brands price their products. If you take a minute to type on Google “the best blenders of 2021”, Ninja has 3 products featured on the top 10 list, further highlighting how highly rated Ninja blenders are on the market. The fast-growing brand has done everything to keep those regards soaring very high, and it’s only a matter of time, with consistency, before it catches up with the supposed big guns.

As powerful and efficient Ninja blenders are, their blades get weaker as you use them regularly, especially if you’re the type that has one or two things to do with the blender each day that passes by. Sharpening Ninja blender blades will help you keep the blender functioning properly, guaranteeing you the best results anytime you put it to use. Some people would rather purchase new blades rather than trying to sharpen the affected ones, and that’s not always the best solution as you can sharpen the old ones rather than getting Ninja blade replacements.

Ninja blenders have four primary blenders with two blades pointing down while the other two blades facing the opposite direction. According to Kitchen Habit in their latest blog post about Ninja blades, the only blades that can be cleaned are the only ones pointing upward. If you notice your blender is no longer giving you the results you want, rather than having the blades changed, Ninja blender blade sharpening will be the best thing to do, after all, it’ll almost cost you nothing.

A high-performance blender like Ninja can do almost anything you can think of as far as food processing is concerned. The things you can task a Ninja blender to do for you besides blending include making homemade smoothies, crushing ice and hard ingredients, pureeing baby food, making coffee drinks, preparing hot sauce milkshakes, and many more. With a blender tasked with all these responsibilities, keeping all its parts clean will not only help you get the best results out of it but also helps you get the best value for your money.

Excessive use and long-term use are not abnormal when you have a high-performance blender like Ninja. This is not only peculiar to Ninja blenders, but others like Cuisinart blenders, Blendtec blenders, KitchenAid blenders, Vitamix blenders, and every other blender present on the market at the moment. Sadly, most Ninja blender users don’t often know what to do when their Ninja blender blades are dull which is what we’re going to be discussing later in this article.

Out of frustration, they always end up going on the market to look for Ninja blade replacements which is not always the best thing to do when you’re faced with the problem of dull blades. Thankfully, there are a few practical steps you can take to clean and sharpen your Ninja blender blades without having to purchase replacements. Before we get into our ultimate guide on how to sharpen Ninja blender blades, let’s take a quick look at some components of a Ninja blender, their uses, and how each of them can be cleaned.

U.S. imports of household and kitchen appliances from 2002 to 2020

Sales of kitchen appliances in the United States over the past few years have skyrocketed, and that can be traced down to people’s appreciation for these appliances. As a result, the import value in the country has also skyrocketed, with the difference between 2002 ($10.43 billion) and 2020 ($33.12 billion) showing the huge progress that has been made in the country over the past few years. This article was created using the information provided by Arne Holst, Statista’s lead researcher for technology and communications.

The appliance industry is a billion-dollar industry, and in 2018, the global consumption of major appliances resulted in an estimated $177 billion, proving again that the industry is a big one. Some of the brands that have contributed hugely to the progress of the industry include Bosch, Siemens Group, Electrolux, LG Electronics, Samsung, Whirlpool, Haier, and many more. Similarly, the United State ranked the largest market for household appliances in 2018 with a market value of around $37.6 billion.

What Components Are Needed In A Blender?

When it comes to versatility, only a few machines can stand toe-to-toe with a blender, but people don’t often realize that until they maximize the functionalities of the versatile machines they have in their kitchens. As most of you already know, some components are featured in your blender that make it function as a unit. If you own a blender, knowing all the parts, what they do, and how to clean them will help you get the most out of your blender when it matters most.

All these components come together to make the blender function properly as a unit, making it the versatile machine we all enjoy today. Below are all the components you can find in a blender, and what each component does.


The motor is one of the most important parts of a blender, and oftentimes, it serves as a deciding factor that can directly impact people’s decision to purchase a particular blender. The power of a motor is measured in watts, and that’s what differentiates high-performance blenders from the conventional ones that don’t boast as much power. The motor is usually located at the blender’s base, and according to Kitchen Seer, the power of your motor is what determines the power of your blades.

Different blenders are packed with different motors, depending on the type of blender it is. As powerful as the motor of your blender might be, you’ll likely need to replace it at least once during the blender’s lifetime. The blender’s motor is an important thing to be aware of when you’re planning to own a blender or you already have one.


There always has to be a seal between the jar and the blades since that’s where operation starts. The or-ring is a flat rubber ring that lies between those two components to ensure that there’s a seal, and that’s why it’s also regarded as one of the most important parts of the blender. The o-ring, as small as it is, plays a pivotal role in keeping the blender functional.

Without the o-ring, food coming from the blender jar can easily get to the motor and damage it in the process, and without the motor, there’s no way the blender can function at all. Always remember that the o-ring can get damaged anytime, especially if your high-powered blender can make hot soup or process hot liquids. Thankfully, they are cheap and you can get them very easily.


Every machine has different components that keep the machine functioning at the highest level. With a blender, the blades play a huge role, especially in a high-powered blender when the blades are tasked with blending, pureeing, crushing, and many others. The blade is usually made of stainless steel, but the quality of the blade depends on the type of blender you’re investing in. The blade is what does the hard work with every task you want to do.

Blender blades are made of two pieces of metal built such that they make a cross shape at the bottom of your blender. Some blenders won’t work if the blades are not attached surely. The blades are attached directly to the motor at the bottom of the blender.


The blender base doesn’t do much; it only serves as a house for the motor as well as the several control buttons. It also houses a cord that can be plugged directly into a power outlet in your kitchen.

Blender Lid

The blender lid is another important part of the blender, and that’s what keeps your ingredients in the jar whenever you’re blending. You may not truly know the importance of the blender lid until you start using a high-powered blender that whips your ingredients at a high speed. What the lid does is keep your ingredients safely in the blender jar so they don’t forcefully escape.

Blender lids usually come with a plastic rubber that helps form tight seals around the blender jar to keep you safe and also help tighten your lid around the blender whenever you’re using it.

Blender Jar

The final piece and one of the most important components of a blender is the blender jar. It is visually understandable as its job is to help you hold your ingredients comfortably so the blades beneath the jar can blend them. Blender jars are available in glass, plastic, or metal, depending on the quality of the blender. Some high-powered blenders come with glass jars with measurement markings on the outside of the jar to make it easier for you to measure your ingredients before putting them in your blender for processing.

We hope by now you’re familiar with all the components of your blender to help you maximize the machine’s functionalities as well as give you the best value for your money. Regular maintenance of all these components will help you keep them in check. Now that you’re familiar with Ninja blender blades use, and what the other components in your blender are, let’s delve into how to sharpen your Ninja blender blades.

How To Sharpen Ninja Blender Blades

What most Ninja blender users do whenever their blender blades get dull is to get Ninja blades replacement, which always appears like the most ideal option until you learn how to shape Ninja blender blades. Thankfully, the steps involved in sharpening your Ninja blender blades are not difficult, but most people don’t know this, and perhaps for safety reasons, they just conclude that purchasing new sets of blades is more appealing. Because blender blades are metal instruments, they can easily be sharpened, and that’s what makes these steps very easy.

Knowing the right approach will help you achieve this task comfortably, but before that, you need to learn all the safety and important tips about caring for your blender as well as its blades perfectly. Check out the important tips below to know how to care for your blender and its blades.

  • Although it is safe to clean your blender blades in the dishwasher, you may not get the best results unless you clean them with your hands. When you’re cleaning the blades with your hands, ensure that you have your protective gloves on all the time.
  • Every Ninja blender comes with a wrench which is typically used for assembling and disassembling the blender blades. Don’t try to use your hands to get the blades off the base, instead, use your Ninja blender wrench for this task.
  • Even if you’re using a wrench to disassemble the blades, always wear protective gloves. When you’re sharpening the blades, always wear your protective gloves because the blades can slip through your fingers and cut you without gloves.
  • Put the blender components in a safe place as soon as you’re done cleaning them after every use.
  • It doesn’t matter if you cleaned your blender before taking it apart the last time. If you’re using it again, you need to clean those parts again before reassembling the parts to the blades.
  • The most important things about your Ninja blender are always in the user manual that comes with every new blender after every purchase. In your user manual, you’ll learn how to properly assemble and disassemble your blender blades as well as other parts of the blender.

To sharpen your Ninja blender blades, below are the steps you need to observe.

Unplug the blender from the power source

Safety is an important thing with every step involved in fixing things, and sharpening your blender blades is not an exception. This is the most important step because it is not ideal for you to try to sharpen your blender blades with your blender still connected to the electricity. If you don’t disconnect the blender from the power source, accidents can occur, and you can get hurt badly.

Disconnect the jar from the base

The blender jar is connected to the base via the o-ring. Removing the jar is the next step to take when you’re trying to sharpen blender blades because you can’t access the blades until you get the blender jar off. Carefully, separate the blender jar, regardless of its material, and clean the jar before keeping it in a safe place. Although cleaning the blender jar is not necessary, it is advised that you do so to keep everything fresh for the next time you’ll be needing the blender.

Separate the blades from the base

You have to be very careful with this step because the blades, as dull as they might seem, can hurt you. Most people don’t know how to get through this step, and if you happen to be in that category, get help from your Ninja blender user manual on how to take the blades off the base. Some people also find the idea of sharpening the blades while they’re attached to the base very appealing, but it’s not safe at all. Always ensure that you have your protective gloves on whenever you’re taking the blades off the base.

Clean the blades

After removing the blades from the base, gently clean the blender blades with white vinegar and a toothbrush. Soak the blades in white vinegar or soapy water for about 20 minutes before carefully cleaning them with a toothbrush. There are lots of ways to clean your blades other than using vinegar solution. You need to explore different options to know which cleaning method you’ll find most appealing.

Sharpen the blades

After cleaning the blades, the next and most important step of this guide is to sharpen the Ninja blender blades. For this part, you’ll need a plate or rod and a blade. The first step involved when sharpening the blades is to put the blade on one hand and a sharpening blade on the other hand. Put the sharpening plate over the blade such that it’s facing the four sides of the blade. Do this for a while until you’re confident that the blades are properly sharpened before you start reassembling the components again.
