If you’ve ever noticed a round hole near the blade of your kitchen knife and assumed it was just for hanging or to make the knife lighter—you’re not alone.

But here's the twist: that seemingly insignificant hole is far more useful than you think.

In fact, it’s a multifunctional design feature that, when used cleverly, can turn your basic kitchen knife into a versatile cooking tool. Today, we’re uncovering 7+ practical and unexpected uses for that little hole in your kitchen knife—ones that can save you time, effort, and even money in the kitchen.

Let’s dive in.

1. Easy Hanging = Better Hygiene & Safety

Let’s start with the obvious: yes, the hole is designed to let you hang the knife on a hook or magnetic strip. But it’s not just for saving drawer space. Hanging your knife keeps the blade dry and clean, reducing the risk of rust, bacterial growth, or accidental cuts when rummaging through a drawer.

🪝 Pro tip: Hang knives vertically with the blade pointing downward to protect the edge and prevent accidental drops.

2. Removing Snail or Shellfish Tails — With Ease

If you love cooking shellfish like snails or sea snails, you know how tedious it is to extract those slippery little tails. Here’s a trick:

Stick your knife vertically into a cutting board so it stands firm, insert the snail tail into the hole, then gently tap it from behind with another utensil. The tail pops right out, clean and intact.

🐚 This hack works particularly well with shelled seafood or anything small and cylindrical that needs a little coaxing.

3. Quick Fruit Corer

No corer? No problem. The hole in your knife can act as a makeshift fruit coring tool. Press the hole over the stem or seed of small fruits like cherries, plums, or even apples, and gently twist or tap.

This method helps remove the core without destroying the fruit's shape — ideal for decorative plating or preserving the aesthetic of your dish.

🍎 Also great for removing cherry pits when making sauces or jams!

4. On-the-Go Knife Sharpener

In a pinch, the hole can double as a simple sharpening slot. Fix the knife (with the hole) into a stable wooden block or board. Then slide another knife’s blade through the hole at a consistent angle. The edges rub gently against the steel, helping sharpen or straighten the blade.

⚠️ Always wear gloves or use blade guards when sharpening this way to avoid injury.

5. Quick Measuring Cup Substitute

Ever find yourself missing a measuring spoon when cooking? The hole on some knives can hold a fixed amount of liquid — usually around 5ml (1 teaspoon), depending on its size. Simply fill it with oil, soy sauce, or vinegar to get a quick measurement when cooking or marinating.

📏 Not ultra-precise, but helpful in a pinch for common liquids or sauces.

6. Improvised Bottle Opener

Yes, you read that right.

The hole in a kitchen knife can help you open bottle caps, especially metal ones. Just insert the edge of the cap into the hole and use the knife as a lever to pop it off.

This trick also works with other metal lids like cosmetic tins or soda cans—just be careful and use a towel to avoid slips.

🍻 Perfect for when you’re camping, cooking outdoors, or just misplaced your bottle opener again.

7. DIY Meat Slicer Guide

Slicing meat evenly is essential for cooking — whether you’re making stir-fry, hotpot, or sandwiches. By placing the meat through the hole, you get a manual slicing guide that helps align your cuts.

This ensures consistent thickness, better cooking results, and more appealing plating. Plus, it saves time compared to freehand slicing, especially if you’re cutting multiple pieces.

🥩 Works best on semi-frozen meat or tender cuts.

Bonus #8: Creative Garnish Tool

Feeling fancy? The round hole can help you create circular cuts or holes in vegetables like cucumbers, carrots, or zucchini for garnishes. It’s a fun way to elevate your dish’s presentation without needing special kitchen tools.

🎨 Want to impress at your next dinner party? Use the knife hole to shape mini fruit skewers or veggie art.
