You can use a classic straight knife for pretty much everything. You can use it to slice cheese, tomatoes, and even some watermelons. Sure, it would be difficult to use for some foods, but at the end of the day, it can be done. However, things are likely to improve when you use specialized knives. Is there a specific knife for watermelons and other similar large fruits?
The truth is that there are knives particularly designed for large round fruits. However, choosing the best watermelon knife could be a bit tricky because there are lots of options out there. Some of them are clearly better than others. It is up to you to research your options and get some reviews or recommendations. Here are the top-rated options based on buyers’ testimonials, as well as the features that make them stand out in the crowd.
What are Watermelon Knives?
Watermelon knives are specifically designed for large fruits. Practically, they are quite versatile and are not built for watermelons only, but for anything in that size. They are just as handy for cantaloupes or other types of melons, not to mention durians, jackfruit, and even dragon fruits. As long as you need to cut through something large, this knife can get the job done in no time.
Given the size of the foods, these knives obviously come with large blades. While it may seem like a thin and super sharp blade could cut through the rind much easier than a long blade, the truth is these knives are wide as well. The blade is pretty thick too. It is also stiff so cutting through thick rind will not flex it or cause it to break.
Watermelon knives are built to be sturdy and durable. They can be used for other foods too and they do not require too much maintenance. Since the blade is usually straight, straightening them is relatively simple. They are less likely to get dull too soon though anyway – after all, they are used for food and not for hard materials.
Other than that, it is worth noting that watermelon knives can come in more shapes and designs. While the long and wide blade is classic, there are more innovative solutions that can cut through watermelon without too much hassle – some knives are built to cut small cubes. They are great for the flesh, but not the best option for the rind.
All in all, here are the best-rated options in commerce.

Frequently Asked Questions
Should I choose stainless steel or high carbon steel for a watermelon knife?
Each material has its benefits and few drawbacks. Stainless steel looks good. It is incredibly good against rust and corrosion. Chances are you will never face such issues – not now and not in 10 years from now. However, it needs to be sharpened more often.
On the other hand, high carbon steel is known for getting incredibly sharp. It is practically razor-sharp – a man could shave his beard with it. Once sharpened, it will retain its edge for long periods of time, so it does not require such frequent operations. But then, it is not as good as stainless steel when it comes to rust, so you will have to store it when dry only. A bit of oil will keep it in good condition if you do not use it too often.
Should I get a double-bladed watermelon knife or a single edge knife?
The double-bladed watermelon knife is not common. In fact, over 99% of all watermelon knives have one edge only. In some parts of the world, this is actually a safety requirement. Therefore, you will have to stick to a single edge. You are less likely to use both edges anyway – unless one of them gets dull and you do not feel like sharpening it.
On the other hand, there are watermelon slicers with double-edged blades.
Is there anything else I can use a watermelon knife for?
The characteristics of a watermelon knife are similar to the characteristics of other specialized knives. For example, it has a long straight blade. This blade is also common in meat knives. Sure, chef knives are suitable for all types of meats, but long pieces will require long blades. In other words, you can use your watermelon knife for meats and other fruits and vegetables as well, so it is a great tool to have around your kitchen.
Are watermelon slicers worth the money?
To help you get an idea, a watermelon slicer should go in the same category as a potato slicer or perhaps an apple slicer. These things are cool to have. It is faster to chop and slice a watermelon yourself. You do not need a device with rotating blades to chop a slice into small cubes, especially as it might crush them.
The best watermelon knife should have a long blade and a sharp edge. These are the main requirements. As for the brand, style, and design, it is up to your personal preferences and needs. Do not make your decision based on looks and design only, as the performance is more important in the long run. A few reviews and recommendations from previous buyers will most likely lead you in the right direction.
