A knife with teeth is called a serrated knife. These special blades have a saw-like edge with small points or "teeth" along the cutting edge. You'll recognize them by their jagged appearance. Unlike straight-edged knives, serrated knives cut through food with a sawing motion rather than a clean slice.
Types of Serrated Knives in Your Kitchen
Several common kitchen knives feature serrated edges. Each one serves a different purpose in your cooking.
Bread Knife
The bread knife is perhaps the most famous serrated knife. It features a long blade (usually 8-10 inches) with wide, deep serrations. These teeth help the knife cut through crusty bread without crushing the soft interior. Additionally, the serrations create less friction, so the knife doesn't drag through the bread.
Steak Knife
Steak knives are smaller serrated knives designed for table use. They typically measure 4-6 inches in length with medium serrations. These teeth easily cut through cooked meats without requiring excessive pressure. Most dining sets include serrated steak knives rather than straight-edged ones.
Tomato Knife
A tomato knife has a serrated edge with smaller, finer teeth.
The blade is usually 5-6 inches long and often includes a forked tip for picking up slices. These specialized serrations cut through tomato skin without squishing the delicate flesh inside.
Utility Knife with Serrations
Some utility knives come with serrated edges. These all-purpose knives handle various kitchen tasks. The serrations make them particularly useful for cutting foods with tough exteriors and soft interiors.
Why Serrated Knives Have Teeth
Serrated knives have teeth for specific functional reasons. First, the pointed teeth contact the food at high pressure points, enabling them to grip slippery surfaces like tomato skin. Meanwhile, the recessed areas between teeth reduce friction during cutting.
The sawing motion used with serrated knives works differently than the straight push or rock cutting of regular knives. When you drag the serrated edge across food, the teeth catch and tear while requiring less downward force. This makes them perfect for foods that would otherwise be crushed under pressure.
Because only the teeth contact the cutting surface, serrated knives stay sharp longer than straight-edged blades. The recessed areas between teeth rarely touch the cutting board, thus preventing them from dulling quickly.
When to Use a Serrated Knife
Serrated knives excel at specific kitchen tasks. Use them when:
Cutting Foods with Different Textures
Foods with a hard exterior and soft interior benefit from serrated knives. For example, crusty bread, tomatoes, and some fruits like pineapples cut cleanly with serrated edges. The teeth grip the tough outer layer without crushing the delicate inside.
Slicing Soft Foods
Cakes, pastries, and soft sandwiches slice cleanly with serrated knives. The teeth prevent these delicate foods from compressing during cutting. Consequently, your baked goods maintain their shape instead of getting squished.
Handling Slippery Items
Serrated knives grip slippery foods like tomatoes and some citrus fruits. The teeth catch the skin easily, whereas a straight blade might slide off the surface. This makes precise cutting much easier and safer.
Carving Roasts and Large Meats
Some larger serrated knives work well for carving cooked meats. The teeth help cut through the exterior crust while still slicing the tender meat inside. However, chef's knives or dedicated carving knives usually work better for this purpose.
Comparing Serrated vs. Straight-Edge Knives
Understanding the differences between serrated and straight-edge knives helps you choose the right tool for each kitchen task.
| Feature | Serrated Knives | Straight-Edge Knives |
|---|---|---|
| Cutting Motion | Sawing back-and-forth | Push cutting or rocking |
| Best For | Foods with tough exteriors, soft interiors | Precise cuts, most general tasks |
| Edge Retention | Stays sharp longer | Requires more frequent sharpening |
| Sharpening | Difficult, requires special tools | Easier, can use standard whetstones |
| Common Types | Bread, steak, tomato knives | Chef's, paring, santoku knives |
Straight-edge knives offer cleaner cuts and more precision for most cooking tasks. However, serrated knives handle specific foods much better due to their toothed design.
Choosing a Quality Serrated Knife
When shopping for a serrated knife, consider these important factors:
Serration Pattern
Look at the number and shape of the teeth. Fewer, larger serrations generally cut bread better, while more numerous, smaller serrations work well for tomatoes and other foods. The shape of the teeth affects how cleanly the knife cuts through different foods.
Blade Length
Choose an appropriate length for your needs. Bread knives should be at least 8 inches long to cut through large loaves. Steak knives work best at 4-6 inches, while utility serrated knives usually measure 5-7 inches.
Handle Comfort
Test the handle comfort since serrated knives require a different motion than straight knives. The handle should provide a secure grip during the sawing motion. Materials like wood, composite, or textured plastic offer good grip even when your hands are wet.
Blade Material
High-quality stainless steel resists corrosion and maintains its serrated edge longer. Some premium serrated knives use high-carbon stainless steel for better performance and durability. The right material ensures your knife serves you well for many years.
Kyoku uses Japanese VG-10 high-carbon stainless steel for our serrated knives. This premium steel holds its edge longer than ordinary stainless steel while resisting corrosion. The result is a serrated knife that stays sharper longer with minimal maintenance.
Caring for Your Serrated Knives
Proper care extends the life of your serrated knives. Follow these simple tips:
Always hand wash serrated knives rather than putting them in the dishwasher. The harsh detergents and water pressure can damage the teeth over time. After washing, dry them immediately to prevent water spots and potential rust.
Store serrated knives properly by using a knife block with appropriate slots or blade guards. Never throw them loosely in a drawer where the teeth can chip against other utensils. Proper storage keeps the serrations sharp and prevents accidents.
Unlike straight-edge knives, don't use a honing rod on serrated knives. Instead, when they need sharpening, use a specialized serrated knife sharpener or take them to a professional. The teeth make traditional sharpening methods ineffective.

4 Common Questions About Serrated Knives
1. Can serrated knives cut vegetables?
Yes, serrated knives can cut vegetables, especially tomatoes and bell peppers. However, for most vegetables, a straight-edge chef's knife provides cleaner cuts. Use serrated knives primarily for vegetables with tough skins and soft interiors.
2. How often should I replace my serrated knives?
Quality serrated knives can last many years with proper care. Replace them when the teeth become damaged or when sharpening no longer restores their cutting ability. Kyoku serrated knives typically last 5-10 years with regular use before needing replacement.
3. Are expensive serrated knives worth the money?
Higher-priced serrated knives typically offer better steel quality, more comfortable handles, and more effective serration patterns. Kyoku offers professional-grade serrated knives at mid-range prices, delivering exceptional value without the premium price tag of luxury brands.
4. Can I sharpen serrated knives at home?
Yes, but it's challenging. You need a specialized sharpening rod that fits between the teeth. Each scallop must be sharpened individually, making it time-consuming. Kyoku offers a knife sharpening service for their serrated knives, ensuring they're sharpened correctly without damaging the teeth.
Conclusion
A quality serrated knife changes how you approach many common kitchen tasks. From effortlessly slicing crusty sourdough to perfectly cutting ripe tomatoes without crushing them, the right serrated knife makes cooking more enjoyable.
