This $10 Tool Will Change the Way You Cut Watermelon
Updated on Apr. 28, 2025
Nothing beats the juicy, refreshing taste of watermelon in summer. But, going through the process of cutting up watermelon into evenly sliced cubes or wedges is a feat. It’s so troublesome it’s probably the reason you pass up the fruit in the grocery store. Luckily, we found a nifty Amazon gadget that takes the pain out of cutting watermelon. Trust us, you’ll never want to cut a watermelon with a knife again.
Meet the watermelon slicer. Fit with an automatic blade that cuts the fruit in perfect squares, it slices up an entire watermelon in under five minutes. If you love juicy, refreshing and evenly cut fruit (who doesn’t?!), a watermelon slicer is the Amazon gadget you didn’t know you needed—and it’s only $9.99!
What’s a Watermelon Slicer?
A watermelon slicer is a quirky kitchen gadget featuring a stainless steel blade that evenly cuts the fruit into squares, ensuring no melon chunks get left behind. Unlike a standard knife, it distributes the watermelon flesh into ready-to-eat cubes, which is ideal for snacking on the fruit, serving it at a party or feeding it to little ones.
The watermelon slicer’s stainless steel structure contains a pinwheel-like automatic blade at the end, which is what dives into the fruit to cut watermelon into even chunks. All it takes is pushing the tool into the watermelon and emptying the cubes in a dish until the entire fruit is neatly cut. It also comes with a melon baller for those who prefer watermelon in ball form, or for scooping out the fruit from hard-to-reach areas.
It’s another one of those cool Amazon products thanks to its one-of-a-kind features that make everyday tasks simpler—and more enjoyable. And if you’re looking for another fun watermelon tool, try a watermelon keg (yes, it’s a thing) to soak up every last bit of tasty fruit juice.
How to Use a Watermelon Slicer
Before whipping out your watermelon slicer, start with a chef’s knife and cut your watermelon into two halves. Amazon reviewers note it’s helpful to slice off the ends of each watermelon half before using the slicer.
Now, it’s time to put the watermelon slicer to work. Level it with the watermelon halve you wish to slice, placing it about half an inch below the rim. Then, using the green push end, move the slicer into the watermelon. The stainless steel knife and automatic pinwheel blade cut the watermelon into cubes as you push the gadget into the fruit. Slide the tool out and dump the watermelon cubes in a dish and repeat until all that’s left is the rind. The included melon baller is handy for getting hard to reach areas, so don’t be shy with it!

FAQ
What is the Best Knife for Cutting Watermelon?
For cutting watermelon, the best knife is a long serrated knife or a large chef’s knife. A serrated knife can easily cut through a tough rind, and the serrations on the blade ensure that it grips the surface of the melon without slipping, so there’s less chance of inadvertently slicing a finger. A sharp 8- or 10-inch chef’s knife is also strong enough to cut through the rind, but is easier to use to cube the melon’s flesh.
Do Watermelon Cutters Really Work?
Yes! If you want to quickly and easily cut uniform cubes, a watermelon slicer is a must-have kitchen tool. Slicers work best on very ripe, seedless melons, and they can be annoying to clean, but if you cut up lots of watermelon—like for kids’ snacks or lunches—you’ll find that it saves you a lot of prep time.
How Do You Cut a Watermelon with a Slicer?
- Select a firm melon that’s ripe. Seedless is best, as the seeds can clog the cutter.
- Cut your watermelon in half, lengthwise, using a sharp chef’s knife or a serrated knife. Then, cut it into quarters or eighths; whichever you find easier to manage.
- Place one section of watermelon flesh side up. With the roller end of your melon slicer facing down, push it through the ripe flesh of the melon. Roll the slicer forward, applying steady pressure; the blade inside the slicer will dice the melon into cubes.
- Repeat, traversing the surface of the watermelon in strips, until all of the ripe flesh has been cubed.
- Clean the slicer right after use, as bits of melon can get stuck between the rollers.
Is a Serrated Knife Better for Watermelon?
While a watermelon cutter is certainly convenient, a serrated knife works well, too. The teeth of a serrated knife grip the rind of the melon and keep the knife from slipping, which is much safer, especially when dealing with a large, unwieldy melon. In addition, because a serrated knife functions sort of like a saw, there’s no need to press too hard to slice through a tough outer skin—simply saw gently back and forth through the melon until halved.
