German vs. Japanese chef's knives: what really sets them apart?

When choosing a high-quality kitchen knife, you’ll quickly come across two major schools of thought: German and Japanese. Both can serve as a versatile “go-to kitchen knife,” but they differ in blade geometry, steel hardness, balance, and the cutting technique they require.

In practice, therefore, it’s not a matter of which is better in general, but which will be better for your cooking style.

Where did these two traditions come from?

German cutlery is historically associated mainly with Solingen, nicknamed the “City of Blades”. It was here that the image of the robust European chef’s knife was born—durable, versatile, and ready for everyday use.

Japanese knives began to develop more significantly only later, when Japan opened up to Western culture. The traditional craft of knife-making gradually adapted to the new style of cooking, giving rise to modern Japanese chef’s knives that combine precision, sharpness, and a specific approach to materials.

What They Have in Common

The differences are often overestimated. Both the German chef’s knife and the Japanese gyuto are primarily versatile knives for everyday use—slicing vegetables, boneless meat, herbs, or general food preparation.

In both cases, you’ll most often find lengths around 18–25 cm, which is the size most chefs use as their main working tool.

Blade shape: rocking vs. push cut

But you’ll notice the difference right from the first cut.

German knives have a more pronounced blade curvature, which naturally supports the so-called rocking motion—a swaying movement where the tip remains on the cutting board and you chop quickly.

Japanese knives are flatter. Thanks to this, they excel at precise cuts—push cuts, slicing, or clean slicing. The cut is smoother and more controlled.

Today, however, the difference is no longer absolute. Modern Japanese knives often combine both approaches.

A Japanese knife is not just one type of steel. It is a whole world of materials

The fundamental difference between German and Japanese knives, however, lies not only in the shape of the blade. The steel is key.

While European knives are relatively consistent, Japanese production offers a wide range of materials—from practical stainless steels to extremely hard powder metallurgy or traditional carbon steels.

This means one thing:

one Japanese knife can be a durable workhorse, while another is an extremely sharp and precise tool.

What specific Japanese manufacturers use

Specific manufacturers beautifully illustrate these differences.

Suncraft works with AUS10, VG10, and SG2 steels.

AUS10 is ideal for everyday use, VG10 offers an excellent balance of sharpness and durability, and SG2 is among the modern high-performance powder steels.

Kanetsugu combines multiple approaches—using VG10 (approx. 60–61 HRC), SPG2, ZA-18, and molybdenum steels. From a single manufacturer, you’ll find both more affordable models and technically advanced knives.

Hokiyama offers an even wider range:

AUS8, AUS10, VG10, Aogami Super (~63 HRC), and SLD (~62 HRC).

From easy maintenance to extreme sharpness.

Kanetsune combines both traditional and modern steels:

DSR-1K6, AUS-10, VG-10, Shirogami (White #2), Blue Steel #2, and SPG2.

What these steels mean in practice

For everyday cooking, it can be simplified:

• AUS8, DSR-1K6, molybdenum steels - durable, low-maintenance, ideal for daily use
• AUS10, VG10 - balanced performance, good edge retention
• SG2/SPG2, Aogami Super, SLD - higher hardness, longer edge retention, more precise cut

So the difference isn’t just Germany vs. Japan, but mainly:

durability vs. performance.

Steel hardness: why Japanese knives hold their edge longer

Generally speaking:

• German knives: approx. 55–58 HRC
• Japanese knives: approx. 60–65 HRC

Higher hardness means:

• longer edge retention
• smoother cut

But also:

• greater brittleness
• more demanding handling

Grinding angle: a detail that makes a difference

German knives usually have a wider blade angle, which increases their durability. Japanese knives have a smaller angle, allowing them to cut more aggressively and with less resistance.

But just as with steels—there are plenty of exceptions and hybrid solutions here as well.

Construction and balance

A German knife is typically:

• heavier
• more robust
• with a full tang

A Japanese knife is typically:

• lighter
• thinner
• more agile

But here, too, the differences are blurring—there are Japanese knives in Western styles and vice versa.

Maintenance: a crucial difference in practice

This is where it’s decided whether the knife will suit you in the long run.

German knives:

• can withstand rougher handling
• forgive mistakes
• are easy to sharpen

Japanese knives:

• require gentle handling
• don’t tolerate bones or prying
• retain their edge longer

One more important thing: the grind isn’t always the same

A common myth is that Japanese knives are always single-beveled. In reality, most modern Japanese chef’s knives are double-beveled and fully suitable for everyday cooking.

The cutting board matters more than you think

Even the best knife won’t perform well if you use it on the wrong surface.

Avoid:

• glass
• stone
• metal

Wood or high-quality plastic is ideal.

So which is better?

It’s entirely up to you.

If you want:

• durability
• versatility
• minimal hassle

go for the German style

If you want:

• maximum sharpness
• precision
• a better cutting experience

a Japanese knife is the clear choice

Summary

The difference between a German and a Japanese knife isn’t about which one is better.

It’s about which approach you prefer.

A German knife is a reliable tool.

A Japanese knife is a precise tool.

And thanks to the wide range of steels—from AUS8 to SG2 or Aogami Super—with Japanese knives, you can choose exactly the character that suits you.
