Consider Before You Buy


1) Slicer Type

It's important to consider what kind of cuts you want to create with your watermelon slicer. 

-If you prefer wedges (with the rind attached), we recommend the melon corer models.

-If you like watermelon cubes (no rind) for fruit salads and platters, go with the windmill slicers.

-If you prefer a solid knife that cuts through the tough watermelon rind with no problems, go for the large watermelon knife

-If you can't decide and you want them all, go with the watermelon slicer set.

-If you want complete control over your cuts for artistic fruit decorations, go with the fruit slicer set.

-If you want a simple watermelon cutter that creates fun shapes for the kids, go with the popsicle shape slicer

2) Versatility

Consider any other fruits you may want to cut. Some of the slicers listed won't work well with other fruits. The corers, for example, are too big to slice up fruits like apples and pears. They do however, cut into cantaloupe nicely. Consider the size and shape of the fruits you will be cutting before making a purchase solely for watermelon. 

3) Arm/Hand Strength

Reading through a lot of the watermelon slicer reviews, the most common complaint was how difficult it was to slice the watermelon. For many of the customers, this was probably due to a lack of reading the instructions. Many of these slicers only work when the watermelon is properly prepared for the job (look at all the pictures for each product. Most will have illustrated instructions to guide you through the proper cut). 

If you don't think you'll have the leverage or hand strength to use the corer or windmill slicer, the watermelon knife is extremely large and sharp. The overwhelming response from customers was how easy it was to cut through the rind. Just a few things to keep in mind. 

4) Mess Created

Watermelons have a messy meat (especially overripe ones). Make sure to account for the mess that will be made with each slicer. Corers will leave relatively little mess, while windmill slicers can send projectile watermelon cubes across the kitchen floor. Just something to keep in mind. 

7 Best Watermelon Slicers

1) Yueshico Windmill Cutter Slicer

  • Cost: Low
  • Warranty: Satisfaction Guarantee 
  • # Reviews: Over 500 Amazon reviews

Dimensions

  • 6.2 ounces
  • Package Dimensions: 11.81 x 2.91 x 1.53 inches

Unique Features

  • Plastic Blade Material (Child Safe and BPA Free)
  • Fun Cutting Style for Kids
  • Creates Small Cubes (Not Slices)
  • Adjustable Thickness (0-2cm)
  • Hole in Handle to Hang Where You Please
  • Good For Appetizer Plates or Fruit Salad

Pros

  • Video of Application By Customer on Amazon Reviews
  • "Cut Watermelon within 2 minutes"
  • "Fun and Simple to Use"
  • "No Truly Sharp Edges
  • "Included Baller Great for Remaining Small, Hard to Reach Places"
  • Easy to Clean

Cons

  • Still Gets a Little Messy
  • Requires Some Hand/Arm Strength
  • Melon Can Get Stuck in the Wheel 
  • Cuts Not Compeltely Even
  • Works Best on Bigger Watermelons

Summary:

This little nifty contraption is the only watermelon slicer that will truly cut your watermelon cubing time in half. While most of these knife engineers looked to make the job easier, the windmill technology focuses on you spending less time cutting those awkward fruits into bite sized pieces. 

The most common response from verified customers, not surprisingly, was how much time it took off their slicing jobs. If you (or your kids) enjoy watermelon often, then you understand the monotony of slicing these huge fruits. The windmill technology also cuts the watermelon into little rectangles (0-2 cm thick cuts), taking the rind completely out of the equation. There are no "sharp" blades (plastic and sheet metal) which makes it pretty kid friendly to use. 

There were a couple complaints about the amount of arm strength it takes to make the cuts. If you thought a traditional knife took too much hand/arm strength to cut a melon, maybe steer clear of this model. A sharper bladed knife might be your best bet. Also, a windmill slicer does not make completely uniform slices. The rectangles will slightly vary in size.

2) FEENM 15" Large Melon Corer

  • Cost: Average
  • Warranty: Unknown 
  • # Reviews: Over 250 Amazon reviews

Dimensions

  • 1.7 pounds
  • Product Dimensions: 12.3 x 2.7 x 13.7 inches

Unique Features

  • Very Large Design for Cutting Watermelon, Cantaloupe, Pineapples, etc.
  • Easy Grip Handles
  • Cuts 12 Slices and 1 Core Slice
  • Sharp, Stainless Steel Blades

Pros

  • Versatile (Can Cut Through Most Larger Fruit)
  • Much Safer than Knife
  • Great for Slicing a Large Amount of Watermelons
  • "Great Time Saver"
  • "Well Worth the Money"

Cons

  • Take Some Power
  • Need a Knife to Cut the Sides Before Slicing
  • Dulls Over Time

Summary:

A larger version of its apple-coring predecessor, this watermelon slicer is everything it advertises. The picture above reveals what happens after a couple solid pushes using your body weight. In a few seconds, this slicer can cut a full sized watermelon into 12 uniform wedges. It's a simple piece of technology that relies on:

1) A Sharp Blade

and

2) Sturdy, Grippable Handles

Two qualities customers remarked unanimously that this slicer possesses.

There were a handful of complaints from customers about the force it took to push the slicer through the watermelon. I'm inclined to believe these customers did not cut slices off both sides of the watermelon (as advertised) before using the watermelon slicer. The round and tough watermelon rind makes it hard for any blade to cut, let alone a blade that cuts the whole thing in one go. If you decide to go this route, know that you'll have to cut a little of the rind off to get anywhere.

3) Hiverst Heavy Duty 10"
Watermelon Slicer

  • Cost: High
  • Warranty: 1 Year Limited 
  • # Reviews: Over 90 Amazon reviews

Dimensions

  • 2.72 pounds
  • Blade Diameter: 10" 
  • Handle to Handle: 14.5"

Unique Features

  • Made of High Quality 304 Stainless Steel 
  • Cuts 12 Slices in Under 10 Seconds
  • Cuts Anything with Diameter Smaller than 9"
  • Heavy Duty, Stainless Steel Handles
  • 1 Year Limited Warranty

Pros

  • "Super Sturdy"
  • Saves Time
  • Cuts Very Close to the Cutting Board (Leaves Nothing Unsliced)
  • Blade Stays Sharp Over Time
  • Simple to Use
  • 1 Year Warranty

Cons

  • Need Good Leverage to Make the Cut
  • Sharp But Blades Still Bend
  • Doesn't Cit Big Watermeons (Bigger than 9")

Summary:

Let's get straight to the point.

What separates this model from the watermelon corer above it?

This model has heavy duty blades that require less force when slicing a watermelon. The overall customer consensus is that this is in fact true. It also has heavy duty steel handles that feel much sturdier than the watermelon corer above. 

However, this watermelon slicer's blade is approximately 5" smaller than the corer above, so if you want the option of cutting bigger melons, this slicer may not be the one for you. This model also does not create a core cut, so if you plan to use it for melons, it will not de-seed.

Overall, A fantastic watermelon slicer with a few restrictions. Weigh out the pros and cons and find what will work best for your needs. 

4) Kuhn Rikon Melon Knife

  • Cost: Average
  • Warranty: Unknown 
  • # Reviews: Over 150 Amazon reviews

Dimensions

  • 8.8 ounces
  • Product Dimensions: 16 x 1.75 x 0.8 inches
  • Blade Length: 11.5" Long (Via Customer Response)
  • Blade Dimensions: 2mm Thick and 4 cm Tall (Via Customer Response)

Unique Features

Pros

  • Best Reviews of All Product on our List
  • Very Sharp Blade
  • "Cuts Like Butter"
  • Great for Bread as Well
  • Large Blade for Large Watermelons
  • "Totally Worth the Purchase"

Cons

  • Lightweight
  • A Little Flimsy
  • Hard to Store Because of It's Length

Summary:

By far, the greatest reviewed watermelon slicer on our list. With just over 150 reviews, this slicer has sustained a 4.7 / 5 star Amazon rating (as of 08/06/2020). Customers seemed adamant on spreading the good word by suggesting things like, "cuts through melons like it was forged with a burning hatred for all things singular" and "if I'm ever stuck on a deserted island, I want this knife with me." When people are happy, they get poetic. Plain and simple.

This knife is long (blade is 12" approximately), sharp (Japanese Steel), and cuts through watermelons like butter. For the price, you really can't beat it. Besides watermelons, people also liked the long, jagged blade for bread, pineapple, and cantaloupe.  

5) YJHome 5 Piece Fruits Slicer, Peeler, Cutter, Corer, and Baller

  • Cost: Average
  • Warranty: 100% Money Back Assurance 
  • # Reviews: Over 4 Reviews

Dimensions

  • 1.69 pounds
  • Package Dimensions: 13.46 x 11.42 x 5.91 inches

Unique Features

  • 5 Piece Knife Set to Get the Perfect Cut for Whatever the Occasion
  • Slicer Makes Wedges
  • Baller Makes Balls
  • Carver Cuts Precision Cuts
  • Corer Used to Take Core Seeds out of Melons
  • Peeler to Peel the Rind (skin)

Pros

  • Versatile (A Knife for All Fruits)
  • Stainless Steel Material
  • Ideal for Fruit Platters

Cons

  • Almost No Reviews
  • No Knife Sheaths

Summary:

This is the ultimate slicer set for those who like to get artsy in the kitchen. If you want to create cantaloupe bowls with a uniformly spiked edge, the corer and precision carver can do it for you in jiffy. While convenient for watermelon, it is not going to be the tool that cuts down your slicing time. It will, however, give you ultimate control over your cuts for all fruits.

6) Riveira 3-Piece Watermelon Slicer, Windmill Cuber and Knife

  • Cost: Low-Average
  • Warranty: Unknown
  • # Reviews: Over 90 Amazon reviews

Dimensions

  • 2.4 pounds
  • Package Dimensions: 18.1 x 8.4 x 1.9 inches

Unique Features

  • Cut, Slice and Cube with these 3 Watermelon Tools 
  • Slicer Makes Wedges
  • Windmill Makes Cubes
  • Knife Cuts Larger Cuts
  • Dishwasher Safe

Pros

  • Large Blade is Very Sharp
  • Windmill Cuts Cubing Time in Half
  • Slicer is Useful For Wedges Without the Rind
  • Very Positive Customer Responses
  • 4.5 / 5 Star Amazon Review (As of 08/06/2020)

Cons

  • "It Takes Practice"
  • Windmill Makes a Little Mess
  • Slicer Design isn't Ideal

Summary:

If you're interested in this awesome set, you can check out the pros and cons of each slicer individually (windmill slicer and the Watermelon Knife). The only new, unreviewed knife here is the curved slicer. If you didn't know, the curved slicer is the funky-looking, curved knife in the picture above. 

While the idea for this knife was good, the engineering isn't sound. If you research this style slicer throughout Amazon, you'll find that none of them reviewed well. A cool addition to the set, but ultimately you'll end up using the watermelon knife and windmill far more often. For the price, you still can't beat it. 

7) TXIN Watermelon Popsicle 
Shape Slicer (2 Piece)

  • Cost: Low

  • # Reviews: Over 10 Amazon reviews

Summary:

Yes, probably the simplest design ever! But it makes all the difference when you're putting on a show for the kids. If you want a fun and creative way of delivering that delicious watermelon to your guests, I can't recommend it enough. Kids and adults alike loved the popsicle shape. It brings something new to the monotony of healthy eating.
