Buying Kitchen Knives: A Guide to Choosing the Right Blades and Storing Them Safely

Anyone looking to buy kitchen knives is faced with a wide choice: an individual chef’s knife, a complete kitchen knife set, a kitchen knife block or a specialist model such as a Nakiri knife, bread knife or vegetable knife. However, not every prominently advertised feature is important in everyday kitchen use. The key factors when choosing are blade length, material, handle design, care requirements and the intended use.

Common Pitfalls When Buying Knives

1. Blade material is advertised without specific details

Descriptions such as “premium steel” or “particularly sharp” do not tell you much on their own. Look for clear information about the blade material, length and care requirements. Stainless steel may be corrosion-resistant, but depending on its construction and use, it still needs thorough cleaning and drying.

2. A large set does not automatically include the right knives

A knife block can be practical if you need to cover several cutting tasks. However, buying knives that are rarely used in everyday life only increases the space and care requirements. For many households, a chef’s knife, a small vegetable knife and a bread knife are enough. Anyone who regularly prepares meat may also need a boning knife or butcher’s knife.

3. “Dishwasher-safe” is confused with low maintenance

Even if a knife is described as dishwasher-safe, heat, detergents and contact with other cutlery can put greater strain on the blade and handle. The ZWILLING kitchen knife from the Gourmet range is listed as dishwasher-safe; nevertheless, hand washing is recommended to protect the blade and handle. Other models, such as the VierSterne set, are expressly not suitable for the dishwasher.

Criteria to Check Before Buying

Blade length and knife shape

A 20 cm chef’s knife provides a versatile working surface for slicing, dicing and chopping. This length is suitable for many tasks, but may be less comfortable for smaller hands or cramped worktops. A shorter vegetable knife is easier to control when working with small ingredients.

A Nakiri knife has a wide, usually straight blade and is particularly suitable for vegetables and herbs. Serrated blades are useful for bread, while a cleaver is designed for robust cutting tasks. A boning knife or butcher’s knife should be sufficiently narrow and easy to control when separating tendons or cuts of meat precisely.

Steel, cutting angle and care

When choosing stainless steel knives, information about the type of steel, hardness or manufacturing process is more useful than general marketing claims. The ZWILLING Gourmet chef’s knife is described as having a FRIODUR ice-hardened special steel blade with a total cutting angle of approximately 30 degrees, or around 15 degrees per side. These technical details make comparisons easier, but do not replace checking whether the knife suits your own cutting technique.

Regardless of the model:

  • Only use stable chopping boards made from wood or plastic.
  • Avoid glass, stone and ceramic surfaces, as they can put strain on the edge.
  • Do not leave knives lying in water.
  • Dry them completely after cleaning.
  • For storage, use a knife block, protective sheath or suitable drawer solution.
  • A honing steel can realign the existing edge; if the blade is blunt or damaged, professional sharpening may be necessary.

Handle, balance and storage

An ergonomic handle should sit securely in your hand and should not cause pressure points during longer preparation tasks. The material and shape are more important than a decorative surface. A knife block protects the blades from loose contact with other kitchen utensils and provides a secure place to store them. Before buying, check the block’s dimensions and the amount of space available on your worktop.

Practical Decision Guide

  • For vegetables and herbs: Nakiri knife or vegetable knife.
  • For bread and baked goods: Bread knife with a serrated blade.
  • For meat preparation: Boning knife or butcher’s knife.
  • For heavy-duty cutting tasks: Cleaver with a sufficiently sturdy handle and suitable blade.
  • For the home, workshop and DIY: Folding knife or utility knife with a locking mechanism and replaceable blades.

Frequently Asked Questions About Buying Kitchen Knives

How many kitchen knives does a household need?

For beginners, three basic types are usually enough: a chef’s knife, a small vegetable knife and a bread knife. A kitchen knife set or knife block can add to this selection if you regularly prepare meat, fish or large quantities of vegetables.

How long do kitchen knives stay sharp?

How long the edge remains sharp depends on the chopping board, cutting technique, quantity of food, cleaning and sharpening. A honing steel can realign the edge between sharpening sessions. Do not cut on glass or ceramic, and store the knives so that the blade does not come into contact with other objects.

Is an expensive knife automatically the right choice?

No. Price should not be the only deciding factor. Blade length, knife shape, handle, material details, care instructions and the actual intended use are more important. If you only occasionally chop vegetables, you may not need an extensive kitchen knife set. For frequent or specialist tasks, however, a suitable individual knife may be the better choice.
