Buying a kitchen knife: types, materials and recommendations for every household

A kitchen knife should cut cleanly, feel secure in your hand and be suited to the food you’re preparing. Yet many buyers choose a model that looks good in the adverts but doesn’t deliver in everyday use. Often, the problem isn’t the brand but the choice of blade shape, material or care requirements.

Common pitfalls when buying kitchen knives

1. “Extremely sharp” without the technical details

A finely sharpened blade isn’t automatically practical in the long term. Blade steel, edge geometry, blade thickness and intended use all play a part. A small paring knife, for example, is ideal for fruit and vegetables, but not for cutting through hard bones. A cleaver, on the other hand, may be too heavy and broad for delicate garnishing.

A serrated blade is no universal replacement for a straight-edged knife, either. It’s particularly well suited to foods with a firm outer skin and soft centre, such as bread and tomatoes, as well as certain types of sausage.

2. Dishwasher-safe is mistaken for easy-care

A dishwasher-safe kitchen knife is convenient to clean. However, frequent dishwasher cycles can put extra strain on the handle or cutting edge due to heat, detergents and contact with other cutlery. For high-quality or particularly finely sharpened blades, hand-washing with mild washing-up liquid is usually gentler.

So check the manufacturer’s information carefully. The ZWILLING Twin Grip paring knife, for example, is described as unsuitable for the dishwasher, while several Victorinox and WMF models are listed as dishwasher-safe.

3. Kitchen knives that are too large for small worktops

A long blade isn’t automatically more versatile. For small kitchens, compact chopping boards or occasional tasks, a vegetable knife, paring knife or utility knife with a blade measuring 8 to 11 cm can be more practical. A chef’s or carving knife measuring 20 to 25 cm, on the other hand, is useful for portioning larger foods, but needs more space and careful handling.

The key things to consider

Knife type and intended use

Choose a blade shape to suit the food you’ll be preparing:

• Vegetable and paring knives: for peeling, trimming, garnishing and preparing small portions of fruit and vegetables.
• Santoku knives: broad, usually straight or slightly curved blades for vegetables, fish and boneless meat.
• Chinese chef’s knives and cleavers: broad blades for slicing and chopping, and, depending on the model and manufacturer’s guidance, more demanding preparation tasks. Only use them to cut bones if this is specifically stated as suitable.
• Bread knives: serrated blades for bread, rolls and firm crusts.
• Steak knives: for cutting cooked meat, as well as pizza and other foods with a firm surface.
• Carving knives: longer blades for portioning roasts, ham, fruit or vegetables.
• Utility knives: a compact all-round option for everyday cutting tasks.

A kitchen knife set can be a good choice if you need several types of knife. If you already own a good chef’s knife, buying a complementary paring or bread knife is often more economical than choosing a large set.

Blade length and weight

Short blades measuring around 8 to 11 cm are easy to control for precise tasks. The Victorinox Swiss Classic Serrated Paring Knife, for example, has a 10-cm blade and weighs 25 g according to the product details. A longer carving knife, such as the Victorinox Fibrox Carving Knife with its 22-cm blade, is better suited to larger foods and cutting even slices.

Weight affects how a knife handles: lighter models are less tiring for small tasks, while heavier cleavers use their own weight to do the work. So consider not only blade length, but also the handle, balance and how long you’ll be using the knife.

Material, edge and care

Stainless steel kitchen knives are corrosion-resistant and easy to use in everyday cooking. Even so, terms such as “Damascus” or “hardened steel” shouldn’t be judged in isolation. Specific details about the blade material, edge, hardness, handle material and cleaning requirements matter more.

To help your knife last longer:

1. Cut only on wooden or plastic boards.
2. Avoid using glass, stone, ceramic or metal as a cutting surface.
3. Don’t use knives to lever, twist or open packaging.
4. Dry knives straight after washing.
5. Store them safely in a knife block, on a magnetic strip or in a blade guard.
6. Don’t continue using damaged blades.

Frequently asked questions about kitchen knives

Which kitchen knife is best for everyday use?

For many households, a combination of a medium-sized chef’s or Santoku knife, a small vegetable knife and a bread knife is enough. If you often portion meat, you could add a longer carving knife. Choose according to the way you actually cook, rather than the number of knives in a set.

How can you keep a sharp kitchen knife cutting well for longer?

Using suitable chopping boards, hand-washing and drying your knife straight away all help reduce unnecessary wear. A honing steel realigns the cutting edge, but it doesn’t replace a proper resharpening for every knife. Don’t use just any standard sharpener on serrated blades.

Is a kitchen knife set worth buying?

A set is worth it if you regularly use several types of knife and the blades included suit the tasks you have in mind. For smaller households, buying individual knives may make more sense. Before ordering, check the blade lengths, handle material, dishwasher suitability and storage options.
