Knife for Cutting Sweet Potatoes Buying Guide

Knife for Cutting Sweet Potatoes

To choose between the knives, I will highlight the parameters that you need to compare them, like:

Blade Length

The blade and its length matter a lot. If the knife is made explicitly for cutting sweet potatoes, even the length of 4 inches will do. If it is a versatile knife, you need a length of at least 5 inches, if not longer.

Blade Length

It is imperative to check the length of the blade and then make a call.

Blade Type

The knife can consist of a serrated blade, a regular, or a hollow one.

serrated blade

A serrated one can help you make fries, cut sweet potatoes, and make decorative garnishing items.

The normal one can not only help you cut sweet potatoes but fruits, vegetables, and so on.

In contrast, the hollow one can help you attain the functionalities of both these knives and is easy to use.

You have to find out which type of blade you prefer and check it before choosing the best knife for cutting sweet potatoes.


Grip plays a crucial role in using a knife. Even if you have the best knife and do not have a proper grip, you will not be able to cut sweet potatoes.

An appropriate knife grip

Similarly, the improper grip will cause hand fatigue, which means that you can't use the knife for more than a few minutes.

To avoid all these problems, find out as much information as you can about the knife's handle and then choose one.

Sharpness Retention

Sharpness retention always depends on the type of blade that the knife uses. If stainless steel consists of a limited carbon, sharpness will be retained very well. But, if its primary material is something else, you might have to resharpen it from time to time.
