Sharpening steel best in test

Sharpening steel best in test (2025) - keep your knives sharp longer

A good sharpening steel is one of the easiest ways to keep your knives in tip-top shape. Instead of grinding away steel, it straightens out the edges that have been bent during use - something that happens every time you cut into something hard, whether it's meat, wood or plastic. In this guide to the best sharpening steels in the test, we'll go over how they work, what sets different models apart and which ones are best for kitchen knives, hunting knives and outdoor blades.

Whether you use your knife daily or just occasionally, a sharpening steel will extend the life of your knife and reduce the need for sharpening. It's easy to use, takes minimal time and gives immediate results. Below you'll find the sharpening steels that perform best, plus advice on what to consider depending on the material and application.


The 6 best sharpening steels

Which sharpening steel is best for you depends on what knives you use and how much work you want to put in. A simple steel will do a good job in the kitchen, while outdoor knives and hunting knives often benefit from a diamond or ceramic steel. No matter what your purpose is, there are several really good options to choose from.

In this list, we highlight six sharpening steels from manufacturers such as Fällkniven, Lansky and Morakniv - all well-known for their quality and performance. Here you will find both classic steels for everyday use and more advanced variants with diamond or ceramic coatings that also work on harder knife steels. Perfect for those who want to keep their edge in top condition without having to resharpen all the time.

Fällkniven Diamond Sharpener D12Pro

This sharpening steel from Fällkniven is no ordinary steel - the entire surface is covered with industrial diamonds from DeBeers, which provides an extremely long-lasting grinding effect. The core itself consists of a well-hardened premium steel that provides real stability when used, regardless of the type of knife.

D12Pro has been tested by independent institutes in the UK, and the results clearly show why it stands out: after over 40,000 strokes, it still works just as well - while other steels in the test gave up after just 4,000. This is a sharpening steel you can rely on for many years, even with frequent use.

Specifications:

  • Surface completely covered with DeBeers diamonds
  • Long life - tested up to 40,000 uses
  • Provides both sharpening and light grinding
  • Stable core made of hardened premium steel
  • Length: 300mm (450mm incl. handle)

Fällkniven Diamond Sharpener D12Pro

Fällkniven Diamond Sharpener D12

Fällkniven D12 is an oval sharpening steel that is designed to quickly sharpen kitchen knives - even those with hard, stainless steel. Thanks to the fine diamond coating, you can regain sharpness in just a few strokes, making it perfect for those who want to keep up the pace in the kitchen without compromising on the result.

The steel is also surface-treated with titanium-aluminum-nitride - an extremely hard material used on exclusive products to provide long durability. D12 effectively recreates the wedge shape of the edge, and the micro-serration that occurs can even improve the cut in certain raw materials, such as fresh bread.

Specifications:

  • Fine diamonds sharpen even hard steels quickly
  • Titanium-aluminum-nitride for long life
  • Oval grip provides stable use
  • Effective for both kitchen knives and all-round use

Fällkniven Ceramic Sharpener C10

Fällkniven C10 is a ceramic sharpening steel that has been specially developed for high-quality kitchen knives. With a grinding surface of 270 mm, it delivers an extremely sharp edge, while being significantly more durable than traditional ceramic bars. The surface has a hardness of 9 on the Mohs scale - almost as hard as diamond.

What makes C10 unique is its shock-absorbing properties. Where many ceramic steels crack when dropped, C10 can withstand a blow from kitchen table height without breaking. This makes it a really practical choice in everyday life, especially if you work quickly and are not always careful with your equipment.

Specifications:

  • Ceramic surface with a hardness of 9 (almost diamond level)
  • Provides a very sharp edge, especially on chef's knives

What is a sharpening steel and how does it work?

A sharpening steel is used to straighten the edge of a knife - not to grind away material in large quantities. When you cut a lot, especially in hard or fibrous materials, the edge bends microscopically. The knife feels dull, but in many cases it is not really dull - it just needs to be straightened. And that is where the sharpening steel comes in.

Classic sharpening steels made of hardened steel do not remove any steel at all. They act as a comb for the edge and restore its shape quickly and easily. Diamond and ceramic sharpening steels, on the other hand, have such hard surfaces that they sharpen easily while straightening the edge. This makes them effective on knives made of harder steel, but they still do not remove as much material as a whetstone or whetstone.

Sharpening steel vs. sharpening stone

It is important to keep these separate:

  • Sharpening steel - straightens the edge (classic), or sharpens lightly at the same time (diamond/ceramic)
  • Hone - grinds away a little material to reshape the edge
  • Sharpening stone - used when the knife is really dull, removes more material and builds up a new edge

A sharpening steel is therefore a maintenance tool, while a whetstone and sharpening stone are for restoration.

When should you use a sharpening steel?

Use a sharpening steel before the knife becomes noticeably dull. A couple of strokes before or after each use are often enough. If you wait until the knife feels dull and requires force - then it is too late for a sharpening steel, and you need to move on to a whetstone or sharpening stone.

With regular maintenance, you will keep your knife sharper longer and avoid unnecessary wear. A sharpening steel is simply your first line of defense against dull knives.

Different types of sharpening steels

There are several different types of sharpening steels, and which one is best for you depends on the type of knife you use and how you want to maintain the edge. All sharpening steels have the same basic purpose - to straighten the edge - but they differ in material, grinding effect and how much they affect the sharpness of the knife.

Classic sharpening steel

The classic sharpening steel is often made of hardened steel without a coating. It straightens the edge without grinding away material, which is gentle on the knife. This is a favorite in many kitchens and is especially suitable for chef's knives that are used frequently but have not become really dull yet.

Advantages:

  • Does not wear down the edge
  • Quick to use
  • Perfect for everyday maintenance

Diamond sharpening steel

A sharpening steel with a diamond coating has more grinding effect than a regular steel. It removes some material from the edge and is therefore suitable when the knife has started to feel really dull. It also works on harder steels where a classic steel won't bite.

Advantages:

  • Sharpens easily and straightens at the same time
  • Also works on hard knife blades
  • Quick restoration of sharpness

Ceramic sharpening steel

Ceramic sharpening steels have a very fine grinding effect and are often used on Japanese or thin knives where precision is extra important. They sharpen easily while straightening the edge. Many ceramic steels are also very hard - but can become fragile.

Advantages:

  • Provides very fine sharpness
  • Suitable for knives with hard steel
  • Good alternative to whetstones for regular maintenance
