Buying kitchen knives: a guide to blades, materials and everyday use

A kitchen knife should cut food cleanly, feel secure in your hand and suit the way you work. But eye-catching product claims don’t always help you make the right choice. A long list of ingredients or a label such as “Damascus steel”, for example, tells you little about whether a knife is suitable for tomatoes, herbs, meat or hard-skinned produce.

Before buying kitchen knives, watch out for these three common pitfalls:

  • Focusing only on sharpness: A sharp kitchen knife may feel impressive at first. But blade stability, cutting-edge geometry and the ability to sharpen the blade again are just as important.
  • Confusing dishwasher-safe with easy-care: “Dishwasher-safe” can be convenient, but heat, water jets and contact with other cutlery can damage the cutting edge. Hand-washing is recommended for many high-quality knives.
  • Buying an oversized knife set: A large knife set often includes several knives with similar uses. For many households, a chef’s knife or Santoku knife, a paring knife and a small fruit knife are enough.

What really matters when choosing kitchen knives

1. Choose the blade shape and length to suit the task

A chef’s knife with a blade around 18 to 22 cm long is suitable for preparing larger quantities of vegetables, herbs, meat and fish. If you prefer a more compact knife and a mainly up-and-down cutting action, a Santoku knife may be a good choice. The broad blade of a Santoku or Chinese chef’s knife can also be used to scoop up chopped ingredients.

A Chinese chef’s knife looks similar to a cleaver, but that doesn’t automatically make it suitable for chopping through bones. Check what it is designed for. For precise tasks such as peeling, trimming and garnishing, a paring knife or fruit knife with a blade around 8 to 11 cm long is easier to handle.

Serrated blades are useful for soft foods with firm skins. A tomato knife cuts through the skin without crushing the flesh too much. Serrated steak knives and pizza knives are designed for cutting through meat fibres and crisp pizza crusts, respectively.

2. Compare materials and sharpening requirements

Stainless steel is easy to care for and resistant to corrosion in everyday kitchen use. However, the exact steel composition, hardness and manufacturing process all affect how long the edge stays sharp. Claims such as FRIODUR, hardened stainless steel or special blade steel should always be considered alongside the care instructions.

A higher hardness rating can help an edge stay sharp for longer, but it doesn’t make it damage-proof. Hard surfaces such as glass, stone or ceramic can damage the blade. Use a suitable wooden or plastic chopping board, and don’t cut bones, frozen food or very hard objects unless the knife is specifically designed for them.

3. Don’t overlook the handle, balance and cleaning

An ergonomic handle should feel secure in your hand when dry and allow you to make controlled cuts. A smooth join between the handle and blade can make cleaning easier, while rivets and the handle material can help provide stability.

Check the care instructions, too. Some of the Victorinox knives and WMF knives featured here are listed as dishwasher-safe. By contrast, hand-washing is recommended for the ZWILLING knives in the ranges featured here. Always follow the manufacturer’s instructions rather than relying on general claims about dishwasher suitability.

  • Store kitchen knives in a knife block, a protective sheath or on a suitable magnetic strip.
  • Use a honing steel or whetstone only if it is suitable for the blade type and recommended sharpening angle.
  • Keep knives out of children’s reach and never try to catch a falling blade.
  • In Germany, follow the legal requirements for carrying and transporting knives in public places.

Frequently asked questions about kitchen knives

How many kitchen knives does a household need?

For everyday food preparation, a chef’s knife or Santoku knife, a small paring knife and a serrated knife for tomatoes, bread or pizza are often enough. A knife set is worth considering if the blades included are suited to different tasks.

How long does a kitchen knife stay sharp?

It depends on the steel, cutting-edge angle, how often you use the knife and how well you care for it. Cutting on hard surfaces, contact with bones or storing a knife loose in a drawer can damage the edge more quickly. Sharpening it regularly and correctly, and using a suitable chopping board, can help it last longer.

Are kitchen knives dishwasher-safe?

Some models are listed as dishwasher-safe by the manufacturer, including certain Victorinox and WMF knives. Hand-washing is recommended for several ZWILLING knives. Always check the specific product description and dry the blade after cleaning.
