When it comes to cutting watermelon, having the right knife can make all the difference between a frustrating, messy experience and clean, satisfying slices. With so many types of knives out there, it can be tricky to know which is best suited for getting perfect watermelon wedges.
What to Look for in a Watermelon Knife
There are a few key factors to consider when choosing a knife to cut watermelon:
- Blade length – A longer blade around 8-10 inches makes it easier to slice through a whole watermelon in one motion.
- Blade shape – A curved or serrated blade will glide through the melon smoothly rather than tearing the flesh.
- Blade material – Stainless steel holds an edge better than cheaper blades.
- Handle – Look for an ergonomic, non-slip handle that feels comfortable in your hand.
- Weight – Heavier knives can make cleaner cuts through watermelon’s thick rind and flesh.
Types of Watermelon Knives
With the key features in mind, here are some of the top options when picking a watermelon cutting knife:
Curved Slicing Knife
A curved blade ensures smooth, even slices that follow the watermelon’s round shape. The added length of 8-12 inches lets you cut all the way through larger melons in one pass. The curve also creates less friction than a straight edge.
Serrated Knife
The teeth on a serrated knife grip the watermelon’s surface and saw through the thick rind and flesh while minimizing tearing and squashing. Serrated edges stay sharp longer than straight edges too.
Kitchen Shears
Sturdy kitchen shears work well for smaller or pre-cut watermelon slices. The dual blades provide more leverage to cut through the tough rind. Look for shears with stronger steel blades that won’t bend under pressure.
Steak Knife
A simple steak knife can tackle watermelon in a pinch. The sharp point pierces the rind easily. However, the shorter, straight blade may require more sawing motion and won’t produce the cleanest cuts.
Santoku Knife
A Japanese-style Santoku knife combines the convenience of a shorter blade with a curved front edge that reduces sticking. The wide blade also helps scoop up sliced melon.
Electric Knife
Electric knives use two serrated blades that vibrate back and forth quickly to sail through watermelon with zero effort. They can be bulky for storage though.
How to Choose the Right Watermelon Knife
Picking the ideal watermelon knife depends on a few factors:
- Size of melon – Small personal-sized melons just require a paring or steak knife while larger, heavy melons call for an 8-10 inch blade.
- Cutting tasks – Slicing whole melons needs a longer, curved blade. Trimming already cut melon is easier with a smaller knife or shears.
- Frequency of use – Those who rarely cut watermelon can get by with a multi-purpose knife, while melon lovers may want a blade dedicated just to fruit.
- Budget – Inexpensive paring or steak knives under $10 work for light duty. For frequent cutting, invest in a quality stainless steel blade.
- Manual or electric – Electric knives provide effortless cutting but lack portability. Manual knives give you more control.

How to Cut a Watermelon with the Right Knife
Once you’ve selected the perfect watermelon knife, proper cutting technique is also key for perfect wedges. Follow these tips:
- Place watermelon securely on a cutting board or non-slip surface.
- Wash the knife blade thoroughly first for best sanitation.
- Start by slicing a small piece off the bottom to create a flat base.
- For large melons, cut down the center to make two even halves.
- Work from the rind inwards and make straight or curved slices.
- Let the knife do the work rather than forcing it.
- Keep fingers curled under when slicing to protect hands.
- Rinse blade periodically if sticky juice builds up.
Storing Cut Watermelon
Proper storage keeps cut watermelon fresh for longer:
- Refrigerate slices within 2 hours of cutting.
- Use a sealed container or wrap in plastic to prevent drying out.
- Consume refrigerated pieces within 5 days.
- Freeze chunks in airtight bags for 2-3 months.
- Add citrus juice or vinegar to maximize shelf life.
Cleaning Your Watermelon Knife
Handle knives carefully right after cutting watermelon since the wet blades can be slippery. Follow these steps to clean properly:
- Rinse under warm water to wash away stickiness.
- Use mild dish soap and a sponge or cloth to remove residue.
- Dry thoroughly with a towel to prevent rusting.
- Inspect for any cracks or damage in the blade.
- Store in a knife block, sheath or drawer where it won’t be damaged.
Conclusion
With so many varieties of knives available, choosing the right tool specially designed for watermelons is essential for clean cuts and safety. A good watermelon knife should have a stainless steel blade at least 8 inches long, with a curved or serrated edge to glide smoothly through the rind and fruit. Well-known brands like Mercer, Wusthof, Global, and Cuisinart all offer excellent watermelon knife options. Combine the perfect knife with proper slicing technique for watermelon wedges ready for outdoor eating all summer long.
