Best Knife To Cut Sweet Potatoes: Buying Guide 

Many people don’t bother considering the essential features when shopping for cutlery. However, it only leads them to the unnecessary hassle and extra costs.

If you buy your first knife with proper reasoning, you won’t need to spend any money in the future. So, let’s take a look at what attributes to consider when shopping for the top-rated knife to cut sweet potatoes. 


Material is always one of the most important aspects of a knife. It not only ensures durability but also contributes to the sharpness and ease of use. You must be wondering what the best material for a knife is. Well, let us enlighten you. 

The best material you can find is high-quality stainless steel. There are multiple perks of choosing stainless steel as a material. For instance, it’s dishwasher-safe most of the time, so you can forget worrying about cleaning. 

Stainless steel is also stain, rust, and corrosion resistant, which makes it more durable compared to other metals. In addition, this material is also less prone to breakage if forged from one single piece of steel. 

That brings us to the second criteria of the material. Make sure that the blade is forged from a single steel piece. It ensures better sharpness and more durability. 

Ergonomic Handle 

Look for a triple-riveted handle when selecting the knife. It should also be full tang and have a finger guard for protection. If the knife is a high-quality product, it’s fair to assume that it’ll be razor-sharp. So, it’s crucial that the knife is safe to use. 

The handle should also be easy to maneuver. If you don’t feel comfortable while holding the knife, it’ll be a lot harder to cut sweet potatoes with precision due to their dense nature. 

Large Blade 

One of the common requirements for cutting sweet potatoes is a large blade. Considering getting a knife with at least an 8-inch blade length. It’ll ensure convenient maneuverability when cutting the potatoes. 

Sharpness And Edge Retention

The requirement for sharpness goes without saying. However, there are a few things to consider regarding sharpness. For instance, the knife should be usable straight out of the box. If it requires sharpening, you should consider other options. 

The next thing to remember is how well the knife retains its sharpness. If you hone your knife regularly, yet it loses its sharpness frequently, it’s not worth the money. You’ll be doing a lot of dicing, mincing, and chopping. 

So, make sure that the knife doesn’t require sharpening very frequently. A high-quality knife will surely retain its sharpness for months.


A bolster is a part of the knife where the blade meets the handle. It balances the knife’s weight in case the blade is heavy. A bolster isn’t a compulsory feature if you choose to go with a lighter blade. 

Even though there are a few downsides to having a full bolster, it’s essential for heavier blades. So, compare this feature with the knife you’re shopping for before deciding on it. 


Many people don’t even know what a tang means. Well, it’s a piece of metal that runs through the handle. Try getting a full tang when getting a knife for sweet potatoes. 

The reason is that experts agree that a full tang can help balance large knives and make cutting more convenient.  


Price is certainly important. No matter what your budget range is, you should always compare the price with the features. Consider alternatives in the same price range if you feel like the features don’t feel enough compared to the price. 

User Reviews

 You’ll be surprised to know the amount of information you can discover from the user reviews. No matter how much you read the labels, you won’t know how the knife actually feels in the hands. User reviews can help a lot in that department.

People often share their experiences and help fellow knife users. Once you’ve shortlisted a few options, it’s time to go through the reviews online. 

Why Sweet Potatoes Are Difficult To Cut?

Numerous people have struggled while cutting sweet potatoes. But what are the reasons behind it? Well, the structure of a sweet potato is quite a bit different from other vegetables. 

Sweet potatoes come with denser consistency, which makes it more difficult for the user to cut through the molecules. It requires more force and precision to cut a sweet potato than any other fruits and vegetables. 

Another unique feature of sweet potatoes that makes it hard to cut them is the high sugar content. The sugar in these potatoes makes the veggie comparatively stickier, hence hard to cut through. 

How To Soften Sweet Potatoes Before Cutting?

Parboiling the potatoes will reduce your work a lot. Parboiling doesn’t entirely cook your sweet potatoes. However, it does make the veggies soft enough to cut through with ease. Go through the steps below to parboil your sweet potatoes and then cut them for your final dish. 

  • Cut each end of the potatoes and then peel them.
  • Take a container and fill it with water.
  • Place it on the stove and wait till the water boils. 
  • Turn down the heat to a minimum and add the sweet potatoes to the water. 
  • Wait for about ten to fifteen minutes and then strain them. 
  • Finally, cut your potatoes in any shape you want with ease. 

Tips For Cutting Sweet Potatoes

  • If you don’t want to parboil the potatoes, you can microwave them. Poke a few holes on each potato and then microwave them for about five minutes if it’s a large one. The time will depend on the potato size. 
  • Avoid storing sweet potatoes in a refrigerator or fridge. Freezing them only makes it more difficult to cut them. 
  • Use a dry and cool place to store them.
