Weetiee Windmill Watermelon Slicer

Watermelon Windmill Cutter

See At Amazon

This watermelon slicing tool by Weetiee is a windmill slicer. It features a long stainless steel track into which the handle slots and the cutting surface is on the other end.

There’s a green nylon water wheel-like component, which is its namesake. Pushing the device into the flesh of a watermelon rotates this windmill and forces its next ‘blade’ down into the melon. Then, as the next piece of the melon pushes that blade, it jettisons the melon cube onto the track and pushes the next ‘blade’ down. This mechanism is what allows the device to produce uniform cubes. This device is also dishwasher safe.


  • This cutter features an automatic windmill cutting design to produce perfect watermelon cubes.
  • The slicer will be easy to clean, usually just requiring a simple rinse.
  • An excellent option to encourage kids to help cut watermelons, as it has no sharp metal blades.
  • Excellent for cutting small cubes of melon for use in fruit salads.


  • This method will take longer than using a large circular slicer or a watermelon knife.
  • This cutter won’t be able to go through tough watermelon rinds, so you’ll have to cut the ends off.
  • Since it isn’t sharp, it may be hard to cut tougher watermelons.

Mannice Extra Large Watermelon Slicer

Extra Large Watermelon Slicer

See At Amazon

This kitchen gadget works just like the ZaH Melon Slicer. This one, however, is sold by Mannice and boasts an 11-inch total blade diameter. This one has fewer ratings on Amazon but appears to be of the same quality. It is also dishwasher safe.


  • This device promises to cut even the most giant watermelons and other melons like honeydew and cantaloupe.
  • Its sharp blade and grip handles make it capable of cutting giant watermelons in one motion.
  • It includes a watermelon corer in the center, allowing you to separate the best piece of the melon.
  • This gadget produces a dozen uniform slices every time.


  • There’s no opportunity to choose your slice size or shape except by cutting the melon in half.
  • Like the other large, round slicer, it’s not easy to store.
  • Cutting through enormous melons will require a fair amount of upper body strength.

Yueshico Windmill Watermelon Slicer

Yueshico Stainless Steel Watermelon Slicer

See At Amazon

This windmill slicer by Yueshico appears very similar to the Weetiee one at first glance. While the primary device, the windmill slicer, is more or less the same, the watermelon baller is included in the purchase. The melon baller is a little scoop that allows you to make balls of watermelon and will be much better at finishing the pieces closer to the rind the windmill slicer can’t reach. However, under product care instructions, the seller recommends handwashing the tools.


  • It doesn’t have any sharp blades, making it kid friendly.
  • It will cut even mini watermelons into over a dozen bite-sized cubes, great for a fruit salad.
  • This slicer comes with an extra watermelon scoop that can make delicious watermelon balls.
  • It is small, and both gadgets will easily fit in your silverware drawer.


  • Without any sharpness to its base plate, it may take a while to get through a whole melon.
  • Unlike other large watermelon kitchen gadgets, it doesn’t separate the core, which has an excellent popsicle shape.
  • The windmill technology jettisons the cubes pretty hard and will likely splash you and make a mess.

Henmon Watermelon Slicer

HENMON Watermelon Slicer

See At Amazon

A large watermelon slicer like the ones by Mannice and ZaH, Henmon’s offers practically all the same qualities. However, Henmon recommends you hand wash it, which will likely get more longevity out of the device. This device has fewer ratings than the other two of its kind, and more of the ratings are negative. However, the overall score is still good and many negative ratings are due to the tool requiring a lot of strength to operate. A windmill cutter will be a better option if you do not have somebody strong or heavy to push down on the device.


  • The sharp blade will cut through a large-sized watermelon better than similar devices with rounded edges.
  • Every individual slice is the same.
  • Non-slip handles to keep your hands from slipping off the slicer as you push the slicer down through the melon.


  • This slicer will take a lot of arm strength if choosing to cut through the entire watermelon
  • It won’t be easy to find a place to store this large device
  • You won’t get much choice on how your slices turn out, as they’re always the same

How To Use A Watermelon Slicer Safely

It is much easier to be safe with a special watermelon slicer than with a knife. The cutting surfaces are often duller, and the method of use is more straightforward, usually requiring only one motion or repetitive motion of the same kind.

Many more cuts are made when using a knife, and keeping your hands out of the way is not easy. With the tools featured above, one must still try to keep their hands out of the way. With the round slicer, the handles will keep both hands occupied, so you must ensure nobody else is in the way.

However, the windmill slicer is duller and wouldn’t be likely to cut you even if it hit your hands. Either way, be mindful of your hand placement and use the tools as intended to reduce the safety risk.

Watermelon Slicer Buying Guide

Full Watermelon

There’s more to choosing a watermelon slicer than just picking the one with the most beautiful box. Several considerations include the type of device, the materials used, the ease of use, and the safety of the cutting method used.


Most specialized watermelon cutting tools are made of stainless steel and plastics like nylon. This is great because they will be durable, resistant, and practical. Usually, a tool like this is dishwasher safe, but it’s best to check on the product page, as some of them will suggest hand washing only to ensure they last longer.


The windmill category of cutting device featured above is very safe because it doesn’t feature sharp metal blades. Instead, the cutting surfaces of this kitchen tool are the metal base plate and the tapered nylon windmill blades. This makes the windmill type of watermelon slicer an excellent choice for kids and offers a fun method of getting bite-sized watermelon cubes.

The large round watermelon cutter is also a safer alternative to a knife because it’d be unlikely anything is caught below the blades. However, they aren’t as safe of a choice as the windmill design as the blades are stainless steel and very sharp. It also takes a lot of force to operate, making it a worse choice for young kids and the elderly.

Ease Of Use

Both types of tools featured above offer simple cutting and slicing methods. Compared to a watermelon knife, each tool straightforwardly cuts the watermelon. There is no guesswork involved with using them, as they can really only be used as intended. With a knife, you can cut the watermelon however you want, but that means you need to have a plan to get the desired piece shape and size.

The large round watermelon cutters are more challenging to use because they require a lot of force when cutting straight through whole melons. However, you can mitigate this by cutting the watermelon in half first. Both of these tools can also cut and slice other melons like honeydew melons and cantaloupes!

Frequently Asked Questions

What’s The Best Way To Slice A Watermelon?

Watermelon Slices

Most people would probably consider a knife the best way to cut a watermelon. After all, a knife cuts the watermelon to any size and shape of pieces you want to serve. It’s easily the most versatile tool for the job, and you can also use it to cut various other fruits and vegetables.

For adults who plan to cut watermelons often, it’s highly recommended to learn how to do so with a knife. If you want a knife set that will be great for cutting and slicing many different fruits and vegetables, you could look into knife sets under $300 or Amazon Basics knife sets!

However, a kitchen tool like a watermelon slicer is an inexpensive and fun way to get the job done! A tool like a windmill slicer cuts the watermelon into perfectly uniform cubes, and the round cutter makes a perfect slice, both of which can be difficult to achieve with a knife. While they’re not quite as multifunctional of a utensil as a knife, they’re much safer for children and those who are clumsy or inexperienced with knives.

They also don’t need to be sharpened, not that I’m sure how you would go about doing that! Also, quite surprisingly, these watermelon cutting tools tend to have a higher number of customer reviews when compared to watermelon knives.

Is Watermelon Slicer Better Than A Knife?

However, sometimes, like in the case of the windmill cutter, it’s more about the experience and making fun little pieces of watermelon. It usually creates a bigger mess than a knife, which can be a downside, but if you’re cutting watermelons, there’s bound to be juice spilling everywhere.

Do You Have To Wash A Watermelon Before Cutting It?

The short answer is yes! You should thoroughly rinse the outside of your watermelon before cutting it. Also, thoroughly wash your hands. This will significantly reduce the chances of bacteria on either your hands or the rind from getting onto the edible flesh of your watermelon. Just think about how much bacteria is on everybody else’s hands who touched the watermelons before you picked yours.

How To Clean A Slicer Easily?

Luckily, most of the time, these tools will only need a quick rinse as watermelon juice is mostly just water. However, if you’re storing the tool away or if it gets particularly messy, it’s a good idea to wash it. Most of these slicers will be dishwasher safe, which is the simplest way to clean them. However, if they recommend you hand wash them, be careful doing so.

It’s recommended to clean the blades of the round slicer like you’d clean a knife, gripping the back of the blade with a sponge and scrubbing along them. If you want a detailed guide on cleaning knives, we’ve got one of those!

What Are The Benefits Of Using A Watermelon Slicer?

Sometimes these tools will even be safe enough to get your kids to help you chop watermelons into fun little pieces!
