What Is a Chef Knife Used For? The Complete Guide to the Kitchen Workhorse
In the culinary world, there is one tool that reigns supreme. It is not the blender, the sous-vide machine, or the fancy copper pan. It is the Chef’s Knife. But for the beginner cook or the enthusiast looking to upgrade their arsenal, the question remains: what is a chef knife used for exactly?
Is it just for chopping onions? Can it handle bones? And why are there so many different shapes and sizes? At KnivesReview.com, we believe that understanding your primary tool is the first step to becoming a better cook.
In this comprehensive guide, we will break down the anatomy, the techniques, the brand battles (like Shun vs. Wusthof), and the essential maintenance required to keep your blade singing.
1. The Definition: What Makes a Chef’s Knife?
A chef’s knife (or cook’s knife) is a multi-purpose blade, typically 8 inches in length, designed to perform 90% of kitchen tasks. It is defined by a blade that tapers to a point and a “belly” (the curved edge) that allows the knife to rock back and forth on the cutting board.
External Definition
According to Le Creuset, “A chef’s knife is among the most versatile knives… The curve of the blade allows for a rocking motion.” Read their full glossary entry here: Le Creuset Glossary: Chef’s Knife.
Anatomy of the Blade
To use it well, you must understand how it is built. High-quality options, like those seen in our best chef knife brands guide, are often forged from a single piece of steel. This brings us to a critical distinction: the difference between stamped and forged knives. A forged knife usually has a bolster (a thick band of steel) for balance, while a stamped knife is lighter and more affordable.
2. The Core Tasks: What Can It Do?
The chef’s knife is the jack-of-all-trades. Here are its primary functions:
- Slicing Meat: Whether it’s raw chicken breast or cooked steak, the length of the blade allows for smooth, long strokes.
- Dicing Vegetables: This is where the knife shines. From onions to carrots, the weight of the blade helps drive through dense produce.
- Mincing Herbs: Using the “rocking motion,” a chef’s knife can turn basil or parsley into fine dust in seconds.
- Crushing Garlic: Using the flat side of the blade (carefully!), you can smash garlic cloves to peel them easily.
What It Is NOT Used For
Despite its versatility, it is not invincible. Do not use your chef’s knife for:
- Butchering Bones: This will chip the edge. Use a cleaver or a heavy-duty poultry shear.
- Frozen Food: Ice crystals are harder than steel. You will snap the tip.
- Bread: While it can cut bread, it will squash the loaf. Read our guide on the best bread knife to see why serrations are necessary.
3. German vs. Japanese: The Great Divide
When shopping for a chef’s knife, you will encounter two main philosophies: The Western (German) style and the Eastern (Japanese) style. This is the core of the best German kitchen knives vs. best Japanese kitchen knives debate.
| Feature | German (e.g., Wusthof, Zwilling) | Japanese (e.g., Shun, Miyabi) |
|---|---|---|
| Blade Profile | More curved (big belly) for rocking. | Flatter profile for push-cutting. |
| Steel | Softer (56-58 HRC), durable, tough. | Harder (60-62 HRC), sharper, brittle. |
| Edge Angle | ~20 degrees per side. | ~15 degrees per side (Razor sharp). |
| Weight | Heavier, feels substantial. | Lighter, nimble. |

4. Chef’s Knife vs. The Rest of the Block
How does the chef’s knife compare to other specialty blades? Understanding these differences ensures you pick the right tool for the job.
Vs. Santoku
The Santoku is the Japanese answer to the Chef’s knife. It is shorter, flatter, and excellent for chopping vegetables. If you prefer an up-and-down chopping motion over rocking, read our guide: What is a Santoku Knife Used For?
Vs. Nakiri
The Nakiri is a rectangular blade designed exclusively for vegetables. It has no tip, so it cannot rock. It is a specialist tool. Learn more here: What is a Nakiri Knife Used For?
Vs. Paring Knife
The Chef’s knife handles the board work; the paring knife handles the air work. For peeling apples or deveining shrimp, the massive blade of a chef’s knife is clumsy and dangerous. See: What is a Paring Knife Used For?
Vs. Serrated Knife
For anything with a hard crust and soft interior (bread) or a waxy skin (tomatoes), the saw-like teeth of a serrated knife are superior. See: What is a Serrated Knife Used For?

A dull chef’s knife is the most dangerous tool in the kitchen because it requires more force to cut, leading to slips. Here is how to keep it safe.
Sharpening vs. Honing
This is a common confusion. Honing (using a steel rod) realigns the microscopic teeth of the blade. You should do this before every use. Sharpening (removing metal to create a new edge) should be done 1-2 times a year.
- For maintenance tools, check our guide on the best knives sharpener.
- If you aren’t comfortable with stones, consider the best knife electric sharpeners for consistent angles.
- For quick touch-ups, the best knife sharpener (manual pull-through) is acceptable for budget knives like the Victorinox.
Storage and Safety
Never throw your chef’s knife in a drawer loose. It ruins the edge and is a hazard. We recommend:
- For Countertops: The best knife set with block keeps blades accessible and safe.
- For Drawers: Use a dedicated knife drawer organizer.
- For Display: Magnetic knife holders are hygienic and look professional.
- For Travel: Professional chefs should invest in the best knife bag for chefs.
⚠️ The Dishwasher Warning
Do not put your chef’s knife in the dishwasher. The heat expands the handle, and the detergent dulls the blade. While there are some best dishwasher safe steak knives, high-carbon chef knives must be hand-washed and dried immediately.
