Buying a Knife Set: How to Choose Kitchen Knives by Size, Material and Use

A knife set can be a practical addition to your kitchen equipment – provided the knives included are suited to the tasks you actually carry out. Home cooks, beginners and more ambitious cooks often look first at the number of pieces or the brand name. However, blade lengths, knife shapes, handle design and care instructions are more meaningful indicators.

Common pitfalls when buying a knife set

1. More pieces do not automatically mean greater usefulness

A 5-piece knife set sounds more comprehensive than a 2-piece knife set. What matters, however, is whether all the components will be used regularly. A set with a chef’s knife, utility knife and paring knife is often more useful for everyday cooking than a selection containing several similar blades.

Before buying, check:

  • Which types of knives are actually included?
  • Is there a chef’s knife or Santoku knife for larger cutting tasks?
  • Does it include a paring knife for fruit and vegetables?
  • Are scissors, a peeler or a knife block included?

2. Understanding marketing claims about sharpness

Terms such as ‘extra sharp’, ‘long-lasting sharpness’ or special hardening processes are difficult to compare without further information. A sharp blade also requires a suitable cutting surface and regular care. Hard foods, bones and frozen ingredients may be unsuitable and can damage the edge.

With branded products such as a Zwilling knife set, Victorinox knife set or Tefal knife set, you should therefore read the specific details about the steel, manufacturing process, cutting angle and care requirements – not just the marketing copy.

3. A knife block is not always fully stocked

A knife set with a knife block can make safe storage easier. Nevertheless, check whether the block actually contains all the accessories shown. According to the product information, the Zwilling PRO Series 5-Piece Knife Block Set includes four knives and a bamboo block; kitchen scissors are not included, even though a corresponding slot is provided.

The most important selection criteria

Number of knives and blade length

For an average kitchen, three different knife shapes are often a sensible starting point:

  • Paring or peeling knife measuring around 8 to 10 cm: for peeling, trimming and preparing small ingredients.
  • Utility knife measuring around 11 to 16 cm: for bread, fruit, vegetables or smaller cuts of meat.
  • Chef’s knife or Santoku knife measuring around 18 to 20 cm: for slicing, dicing and chopping.

A 3-piece knife set can cover these basic tasks. A 2-piece knife set is suitable if you already have a chef’s knife or initially only need two additional knives. A 5-piece knife set offers greater specialisation, but also requires more storage space.

Blade material and manufacturing method

Stainless steel is widely used in kitchens because it can be corrosion-resistant when properly cared for. Terms such as ‘FRIODUR-ice-hardened’ or ‘SIGMAFORGE’ are specific designations from the respective product data and should not be taken as a blanket promise of performance.

Look out for:

  • Blade material: for example, rust-resistant stainless steel.
  • Manufacturing method: stamped or forged from a single piece.
  • Blade length: it should suit the size of your hand and your chopping board.
  • Edge design: straight blade, granton edge or broad Santoku blade.
  • Care instructions: hand washing can help extend the useful life of the blade and handle.

A Japanese knife set with a Santoku knife and Nakiri knife is particularly suited to people who slice vegetables and fish or prepare fine slices. The Santoku is versatile, while the Nakiri has a straight edge designed for vegetable preparation.

Handle, balance and safe storage

An ergonomic handle should sit securely and comfortably in your hand, which should be dry. Plastic handles are easy to clean, while wooden handles usually require more care. Three rivets, a full tang or a finger guard may be design features, but they do not replace safe cutting technique.

Use a stable chopping board, cut away from your body and store sharp knives out of children’s reach. If you are unsure, follow the care recommendations provided by the manufacturer. ‘Dishwasher-safe’ does not automatically mean that using a dishwasher is the preferred way to clean the knives if you want to maintain long-term blade sharpness.

Care and safe everyday use

Clean kitchen knives as soon as possible after use with warm water and mild washing-up liquid. Dry the blade completely before placing it in a knife block, protective sheath or on a magnetic strip. Avoid using glass or stone surfaces as chopping boards, as they can put considerable strain on the edge.

Depending on the blade shape, a honing steel, whetstone or suitable sharpening system may be appropriate for sharpening. Read the manufacturer’s care instructions beforehand. Knives with damaged, chipped or bent blades should no longer be used.

If you often prepare meat, fish or larger cuts, you may also want to consider a suitable butcher’s knife set. These sets are designed for different cutting tasks from a classic kitchen knife set.

Frequently asked questions about knife sets

Which knife set is suitable for cooking beginners?

For getting started, a 2-piece or 3-piece knife set with a paring knife, utility knife and chef’s knife is often sufficient. The important thing is that the knives perform different tasks and feel comfortable in your hand. A more comprehensive set is worthwhile if you regularly prepare meat, fish and vegetables with the appropriate blades for each.

How long does a knife set stay sharp?

The lifespan of an edge depends on the cutting surface, frequency of use, food being prepared and care. There is therefore no universally applicable timeframe. Hand washing, drying the knives immediately and sharpening them regularly can help maintain their performance. Frozen foods and bones should only be handled with knives specifically designed for these tasks.

Is a kitchen knife set dishwasher-safe?

This depends on the individual product. Some sets, including certain Tefal models, are described as dishwasher-safe in the product information. For other knives, hand washing is recommended or explicitly required. The manufacturer’s instructions should take priority, as heat, detergents and contact with other items can put strain on the blade and handle.
