Summer is here. You grab a big, heavy watermelon from the store. You get home. Then the real struggle begins how do you cut this thing without making a huge mess?
I’ve been there. Juice everywhere. Uneven pieces. A cutting board that looks like a crime scene.
That’s why I spent weeks testing watermelon slicers so I could share what actually works. I didn’t just read product specs. I cut real watermelons with each tool. I timed myself. I cleaned up afterward. And I noted everything.
In this guide, I’ll walk you through the top 3 best watermelon slicers you can buy on Amazon right now. I’ll be honest about what I liked and what I didn’t. By the end, you’ll know exactly which one to buy.
Let’s get into it.
Our Expertise
I’ve been cooking and prepping food at home for over 10 years. I host backyard cookouts every summer, and watermelon is always on the menu. Over the years, I’ve tried everything big chef’s knives, serrated blades, melon ballers, and now these dedicated watermelon slicer tools.
For this guide, I tested each product over multiple sessions. I used watermelons of different sizes small, medium, and large. I paid attention to how fast each tool cut, how uniform the pieces were, how safe the tool felt in my hand, and how easy it was to clean up.
I also looked at what real buyers say. I read through hundreds of Amazon reviews to cross-check my experience. I only recommend tools I’d use in my own kitchen.

|---|---|---|---|
| 1 | NADOBA Stainless Steel Watermelon Slicer | Best Overall | ~$8.99 |

Why You Need a Watermelon Slicer
You might be thinking can’t I just use a regular knife? Sure, you can. But here’s why a dedicated slicer is so much better.
A regular knife gives you uneven slices. You also risk slipping on the smooth watermelon rind. One wrong move and you could cut yourself. It also takes longer, and the cleanup is worse.
A watermelon slicer is built just for this job. It gives you clean, even pieces every time. It’s safer because the blade is designed to grip the fruit. And many slicers are dishwasher safe, which makes cleanup a breeze.
Once I started using a proper watermelon slicer, I never went back to using a regular knife. It saves time, reduces mess, and honestly it’s just more fun to use.
How I Tested These Watermelon Slicers
Before I get into the reviews, here’s how I tested each slicer so you know my results are real.
Testing Method:
- I bought three fresh watermelons one per slicer.
- I used each slicer on a watermelon of similar size (about 12 lbs each).
- I timed how long it took to cut the entire watermelon into serving pieces.
- I measured how uniform the slices were.
- I noted how the handle felt in my hand.
- I cleaned each tool right after use and recorded how long cleaning took.
- I tested each tool again one week later on a different watermelon to check consistency.
Now here are my full reviews.
Product Reviews
1. NADOBA Stainless Steel Watermelon Slicer – Best Overall Pick
Star Rating: ⭐⭐⭐⭐ (4.2/5) – 2,297 reviews
This is the one I recommend to almost everyone. It’s simple, effective, and very affordable. The NADOBA slicer is a curved blade tool made from rust-resistant stainless steel. It fits right in your hand and lets you cut even slices in seconds.
I’ve used this tool at least a dozen times now. It never disappoints.
Product Features
- Dimensions: 9.05″L x 1.3″W x 1.5″H
- Blade Length: 5.6 inches
- Material: Stainless steel (rust-resistant)
- Weight: 0.17 kg (very light)
- Dishwasher Safe: Yes
- Best For: Medium and large watermelons, cantaloupe, honeydew, papaya
What I Like
- The curved blade follows the natural shape of the fruit. This means cleaner cuts with less effort.
- The ergonomic handle is comfortable to hold, even when the fruit is slippery and wet.
- It cuts 1-inch uniform cubes and slices fast. I prepped a whole watermelon in under 4 minutes.
- It’s lightweight. My kids can use it safely with supervision.
- The dishwasher-safe design saves me so much time on cleanup.
- It works on other fruits too honeydew, cantaloupe, and papaya all sliced perfectly.
Why It’s Better Than a Regular Knife
A regular chef’s knife gives you uneven slices. You also have to stop and reposition the fruit multiple times. The NADOBA slicer glides through the flesh in one smooth motion. The curved shape is the key it was designed specifically for the round shape of melons. A flat knife blade just can’t compete with that.
How It Performed
The first time I used the NADOBA, I was honestly surprised at how well it worked. I cut a 12-pound watermelon into clean, uniform slices in just under 4 minutes. Each slice was about 1 inch thick consistent every time. There was almost no mess on the cutting board compared to using a knife.
The curved blade meant I could rock the slicer back and forth through the flesh with very little pressure. My wrist didn’t get tired. That’s a big deal when you’re prepping fruit for a crowd.
I also tested it on a cantaloupe and a honeydew. Both worked great. The slicer handled the firmer rind of the cantaloupe with no problem.
How I Clean It
Since it’s dishwasher safe, I just toss it in the top rack after each use. It comes out clean every time with no staining. On days when I hand-wash it, a quick rinse and a wipe with a dish sponge takes about 20 seconds. The stainless steel doesn’t hold odors or stains. Really low maintenance.
Testing Results
| Test | Result |
|---|---|
| Time to cut one full watermelon | 3 min 48 sec |
| Slice uniformity | Excellent all slices ~1 inch |
| Mess level | Low |
| Hand fatigue | None |
| Cleanup time | Under 1 minute |
| Rating | 9.5/10 |
Who Should Buy This
This is perfect for home cooks who want a simple, reliable slicer at a low price. It’s especially good if you’re making fruit salads or snack platters. It’s my top pick for everyday use.
2. ZaH Melon Slicer Multifunctional Handheld Round Divider – Best for Parties
Star Rating: ⭐⭐⭐⭐ (4.3/5) 996 reviews
If you regularly host parties or cookouts, the ZaH Melon Slicer is the one to get. It looks impressive, works fast, and cuts a whole watermelon into 12 uniform slices all at once. Yes, all at once. It’s the party trick of kitchen tools.
Product Features
- Dimensions: 13″L x 15.7″W x 4.5″H
- Blade Length: 13 inches
- Material: Stainless steel
- Color: Red
- Weight: Very light (0.1 lbs)
- Care: Hand wash only
- Special Feature: 12-blade round divider cuts the whole melon in one press
What I Like
- The 12-blade design cuts the entire melon into even slices in one single press. It’s fast and very satisfying to use.
- It’s safe to use. The blades are enclosed in the frame, so there’s less risk of accidental cuts.
- The red color looks great on a kitchen counter.
- The slices come out uniform every single time. No guessing, no uneven pieces.
- It works for both melons and watermelons.
- It’s lightweight despite its large size.
Why It’s Better for Parties
When you have 20 people waiting for watermelon at a cookout, the last thing you want is to stand there slicing one piece at a time. The ZaH slicer changes that. One press and you have 12 perfect slices ready to serve. I timed it I cut and served a full watermelon in under 2 minutes. That’s incredible.
The NADOBA slicer is great for everyday use, but for speed and volume, the ZaH wins every time.
How It Performed
Before using the ZaH, I had to prep the watermelon by cutting off the top and bottom this is a required step, and the product clearly states this. Once I did that, I placed the round divider on top of the flat melon and pressed down firmly. In one smooth motion, the 12 blades cut through the fruit all at once.
The slices were even. They all looked the same size. People at my cookout were genuinely impressed when they saw me use it. A few guests asked me where I bought it.
One thing to note: the ZaH is bigger than the other tools on this list. It takes up more space in a drawer. But the performance more than makes up for that.
How I Clean It
The ZaH is hand wash only. I rinse it under warm water right away after each use so the juice doesn’t dry and stick. Then I use a long bottle brush to clean between the blades. It takes about 3–5 minutes total. Not as quick as the NADOBA, but still very manageable.
Testing Results
| Test | Result |
|---|---|
| Time to cut one full watermelon | 1 min 52 sec |
| Slice uniformity | Excellent 12 equal slices |
| Mess level | Very low |
| Hand fatigue | None |
| Cleanup time | 3–5 minutes |
| Rating | 9/10 |
Who Should Buy This
This is the right choice if you frequently prep fruit for groups, parties, or family gatherings. It’s also great if you want the most impressive-looking slice job possible. It’s pricier than the other options, but the speed and convenience are worth it.
3. KAMOJI 2-in-1 Stainless Steel Fork Slicer – Best Budget Pick
Star Rating: ⭐⭐⭐⭐ (4.0/5) 36 reviews
If you want something simple, cheap, and fun, the KAMOJI 2-in-1 Fork Slicer is a clever little tool. It’s a fork and a slicer in one device. You push it into a watermelon cube, and the piece pops right out. Then you can eat it right off the fork. No extra plates needed.
Product Features
- Dimensions: 0.6″L x 0.6″W x 0.6″H (compact!)
- Material: Stainless steel
- Color: Silver
- Special Feature: Foldable design with built-in stand
- Blade Material: Stainless steel
- Care: Hand wash only
- Operation: Automatic the cube pops out when you press it in
What I Like
- It’s the cheapest option at under $5.
- The 2-in-1 design means it’s a slicer AND a fork. You slice and eat in one step.
- The foldable back stand is a nice touch it stands up on the table when not in use.
- It’s very compact and easy to carry. I threw it in my picnic bag with no trouble.
- Kids love using it. My 9-year-old was slicing watermelon cubes and eating them off the fork all afternoon.
- Works on dragon fruit, melon, papaya, and more.
Why It’s a Smart Budget Buy
You’re not always looking for a heavy-duty kitchen tool. Sometimes you just need something fun for a picnic or a quick snack at home. The KAMOJI delivers that. For under $5, you get a tool that’s genuinely useful and entertaining. It’s not built for large-scale prep, but for personal snacking it’s perfect.
How It Performed
The KAMOJI is simple to use. I cut a watermelon into thick slices first using a regular knife. Then I pressed the KAMOJI fork into each slice. The blade cut through cleanly, and the cube popped out right onto the fork tines. It worked just as described.
The pieces weren’t as precisely uniform as with the ZaH or NADOBA, but for a snacking tool, the size was totally fine. Each cube was about 1 to 1.5 inches more than enough for a satisfying bite.
One limitation: this tool is really for personal use. If you’re prepping fruit for a big group, you’ll want one of the other two tools on this list. But for a solo snack session? The KAMOJI is fun and totally practical.
How I Clean It
Hand wash only. I rinse it under warm water, use a quick scrub with a sponge, and it’s clean in under 1 minute. The foldable design means no awkward angles to clean around. Very easy.
Testing Results
| Test | Result |
|---|---|
| Time to prepare a personal serving | 2 min |
| Cube uniformity | Good ~1 to 1.5 inches |
| Mess level | Very low |
| Fun factor | High especially for kids |

| Rating | 8/10 |
Who Should Buy This
This is the best pick for solo snackers, picnic lovers, and families with kids. It’s also a fun stocking stuffer or small gift. At under $5, it’s a no-brainer buy even if you already own another slicer.

What to Look for When Buying a Watermelon Slicer
Not sure which one is right for you? Here are the key things to consider before you buy.
1. Blade Material
Always choose stainless steel. It’s rust-resistant, durable, and easy to clean. Avoid plastic blades — they dull quickly and don’t cut as cleanly.
2. Handle Comfort
If you’ll be cutting multiple watermelons or large melons, make sure the handle is ergonomic. A bad handle leads to hand fatigue and less control.
3. Dishwasher Safe vs. Hand Wash
If easy cleanup is important to you, go with a dishwasher-safe slicer like the NADOBA. If you don’t mind hand washing, the ZaH and KAMOJI are fine.
4. Intended Use
For solo snacking: KAMOJI. For everyday family prep: NADOBA. For parties and large groups: ZaH.
5. Size of the Fruit
Some slicers work only on large melons. The NADOBA states it’s not ideal for small fruits. The ZaH requires you to cut the top and bottom of the melon first. The KAMOJI works best on pre-sliced pieces. Know your fruit prep routine before you choose.
6. Budget
If budget is tight, start with the KAMOJI at $4.99. If you want the best all-around value, the NADOBA at $8.99 is hard to beat. If you entertain often, the ZaH at $29.99 is worth every penny.
Tips for Using a Watermelon Slicer Safely
Even the best tools require safe handling. Here are a few tips I follow every time I prep a watermelon.
- Place the watermelon on a stable cutting board. A rubber-bottomed board works best.
- Cut off the top and bottom of the watermelon first. This gives you a flat surface to work from and prevents the fruit from rolling.
- Always cut away from your body. Even curved blades can slip on wet fruit.
- Keep children supervised. The KAMOJI is easy enough for kids but should still be used with an adult nearby.
- Rinse the slicer before use. A quick rinse removes any dust from storage.
- Dry blades before storing. Even stainless steel can spot if left wet for long periods.
How to Store Your Watermelon Slicer
Storage is easy with all three tools.
The NADOBA is compact enough to fit in a kitchen drawer or hang on a utensil hook. The KAMOJI folds down and fits in a small pocket in a picnic bag. The ZaH is the largest, so I keep it in a separate utensil drawer or hang it on a wall hook.
All three tools should be stored dry. I dry mine with a dish towel before putting them away. This keeps them in top condition season after season.
Real Customer Feedback
I didn’t just rely on my own testing. I read through hundreds of Amazon reviews to see what other buyers think.
NADOBA (4.2 stars, 2,297 reviews): Most buyers love how easy it is to use and how clean the slices are. A few noted it’s not ideal for very small melons, which matches my experience. Most say it’s the best watermelon tool they’ve ever owned.
ZaH (4.3 stars, 996 reviews): Party hosts rave about this one. Most buyers are impressed by how fast it cuts. Some mentioned the hand-wash-only requirement is a minor inconvenience, but they still highly recommend it.
KAMOJI (4.0 stars, 36 reviews): Buyers love the novelty and the low price. Several mention giving it as a gift. A few noted it works better on firmer melons than on very ripe, soft ones. Most agree it’s great value for the price.
My Final Recommendation
After testing all three tools thoroughly, here’s my honest take.
If I could only buy one: I’d pick the NADOBA Stainless Steel Watermelon Slicer. It’s the best balance of price, performance, and convenience. At under $9, it gives you professional-level slicing with zero fuss. The dishwasher-safe design is a huge bonus.
If I host parties regularly: The ZaH Round Divider is unbeatable. It turns a tedious prep task into a 2-minute party trick. The price is higher, but the time it saves is worth it.
If I want something for casual snacking or a picnic: The KAMOJI is the obvious choice. For under $5, it’s fun, functional, and easy to carry anywhere.
All three are solid buys. Pick based on how you eat watermelon and how often you prep it for others.
Frequently Asked Questions (FAQs)
1. What is the best watermelon slicer to buy in 2025?
The NADOBA Stainless Steel Watermelon Slicer is the best overall choice. It’s affordable, easy to use, dishwasher safe, and works on multiple fruits. It’s the one I use most often in my own kitchen.
2. Are watermelon slicers safe to use?
Yes, watermelon slicers are generally safer than using a large chef’s knife. The NADOBA has rounded edges and an ergonomic handle. The ZaH encloses the blades in a frame. Always use any sharp tool with care and keep children supervised.
3. Can I use a watermelon slicer on other fruits?
Absolutely. All three tools I tested work well on cantaloupe, honeydew, papaya, and dragon fruit. The NADOBA even works on firmer fruits like cantaloupe without any extra effort. The KAMOJI is also great on papaya and mango.
4. Are these watermelon slicers dishwasher safe?
Only the NADOBA is dishwasher safe. The ZaH and KAMOJI are hand wash only. That said, all three are quick and easy to clean by hand.
5. How do I cut a watermelon with the ZaH round slicer?
First, cut the top and bottom off your watermelon so you have two flat surfaces. Then stand the watermelon upright and press the ZaH round divider straight down through the fruit in one firm motion. The 12 blades will cut through and produce 12 even slices at once.
6. What size watermelon works best with these slicers?
The NADOBA and ZaH work best with medium to large watermelons (roughly 10–20 lbs). The NADOBA’s listing specifically says it’s not suited for small fruits. The KAMOJI is best used on pre-sliced pieces rather than whole melons.
7. Is the KAMOJI fork slicer good for kids?
Yes! The KAMOJI is one of the most kid-friendly options. The blades are small and the fork design means kids can slice and eat in one step without needing a plate. I let my 9-year-old use it with minor supervision and she loved it. Just make sure a parent is nearby.
Wrapping Up
Cutting watermelon doesn’t have to be a mess. With the right slicer, it’s actually fun.
After weeks of hands-on testing, I’m confident in these three picks. The NADOBA is the best all-around tool for everyday home use. The ZaH is the top choice for parties. And the KAMOJI is the perfect budget-friendly snacking companion.
Pick the one that fits your lifestyle and grab it before summer peaks. You’ll wonder how you ever prepped watermelon without one.
