VG10 vs AUS10 Steel: 
Which Knife Steel Is Better?

VG10 vs AUS10 Steel: The Complete Knife Steel Comparison Guide

Choosing the right knife steel is one of the most important—and most confusing—decisions when buying a quality kitchen knife. Two of the most commonly compared steels in Japanese and Japanese-style knives are VG10 and AUS10.

Both steels are stainless.
Both are widely used in high-quality knives.
Both have strong reputations.

Yet they behave very differently in real kitchens.

This guide explains VG10 vs AUS10 steel in depth, cutting through marketing claims and steel hype to show how each performs in terms of sharpness, edge retention, toughness, corrosion resistance, sharpening, and long-term value.

If you’ve ever wondered “Which steel is better for me?”—this article will give you a clear, honest answer.

Why Knife Steel Matters (But Not How Most People Think)

Knife steel matters—but not in the simplistic way many brands present it.

Steel affects:

  • How sharp a knife can get
  • How long it stays sharp
  • How easily it sharpens
  • How likely it is to chip
  • How forgiving it is in daily use

However, steel name alone does not determine performance.

Two knives made from VG10 can feel completely different. The same is true for AUS10. Why?

Because steel performance depends on:

  • Heat treatment
  • Blade geometry
  • Edge angle
  • Grind quality

Still, understanding the inherent tendencies of VG10 and AUS10 helps you choose the steel that best matches your cooking style and maintenance tolerance.

What Is VG10 Steel?

VG10 Steel Overview

VG10 is a premium Japanese stainless steel developed by Takefu Special Steel Co. in Japan.

It became popular because it offers:

  • High hardness potential
  • Strong corrosion resistance
  • Excellent sharpness
  • Long edge retention

VG10 is often positioned as a “high-end” stainless steel—and in many cases, it earns that reputation.

Typical VG10 Steel Composition (Simplified)

VG10 generally includes:

  • Carbon (for hardness and edge retention)
  • Chromium (for corrosion resistance)
  • Vanadium (for wear resistance)
  • Cobalt (for strength and hardness stability)

This alloy mix allows VG10 to reach higher hardness levels than many entry-level stainless steels.

Typical Hardness (HRC)

Most VG10 knives are hardened to:

HRC 60–62

This higher hardness is a major reason VG10 knives:

  • Hold an edge longer
  • Feel sharper
  • Cut more cleanly

But higher hardness also introduces tradeoffs.

What Is AUS10 Steel?

AUS10 Steel Overview

AUS10 is a Japanese stainless steel made by Aichi Steel. It is part of the AUS steel family (AUS6, AUS8, AUS10).

AUS10 sits at the top of the AUS lineup and is often compared directly to VG10.

AUS10 is known for:

  • Excellent toughness
  • Good corrosion resistance
  • Easier sharpening
  • Forgiving edge behavior

While sometimes positioned as “less premium” than VG10, AUS10 excels in real-world kitchens.

Typical AUS10 Steel Composition (Simplified)

AUS10 includes:

  • Carbon (slightly less than VG10)
  • Chromium
  • Molybdenum
  • Vanadium (lower than VG10)

This composition favors toughness and balance over extreme hardness.

Typical Hardness (HRC)

Most AUS10 knives are hardened to:

HRC 58–60

This slightly lower hardness has significant implications for usability and durability.

Sharpness: VG10 vs AUS10

How Sharp Can Each Steel Get?

Both VG10 and AUS10 can get extremely sharp—but VG10 has the edge.

VG10 Sharpness

  • Takes a very fine edge
  • Feels “crispy” and precise
  • Excellent for push cutting and slicing

AUS10 Sharpness

  • Gets very sharp, but not quite as refined
  • Feels slightly “toothier”
  • Excels at aggressive cutting tasks

In practice:

  • VG10 feels sharper
  • AUS10 feels more forgiving

Does This Matter in Daily Cooking?

For most home cooks:

  • The difference is noticeable but not dramatic
  • Technique matters more than steel

Advanced users may appreciate VG10’s extra refinement, while everyday cooks often prefer AUS10’s forgiving feel.

Edge Retention: How Long Do They Stay Sharp?

VG10 Edge Retention

VG10 holds an edge longer due to:

  • Higher hardness
  • Higher wear resistance

This means:

  • Fewer sharpening sessions
  • Longer time between touch-ups

AUS10 Edge Retention

AUS10 holds an edge well—but not as long as VG10.

However:

  • It loses sharpness more gradually
  • It responds very well to quick touch-ups

In real kitchens, AUS10 can feel “consistently sharp” because it’s easier to maintain.

Practical Edge Retention Comparison

VG10: Sharper for longer, but needs proper care

AUS10: Slightly less retention, but easier upkeep

Neither steel is “bad” at holding an edge.

Toughness & Chipping Resistance

This is where the biggest difference appears.

VG10 Toughness

Because VG10 is harder:

  • It is more brittle than AUS10
  • It can chip if misused

Common causes of VG10 chipping:

  • Twisting during cuts
  • Hard cutting boards
  • Bones or frozen foods
  • Overly aggressive edge angles

VG10 is not fragile, but it demands respect.

AUS10 Toughness

AUS10 is tougher and more forgiving:

  • Resists chipping better
  • Handles lateral stress more gracefully
  • Better suited for less-than-perfect technique

This makes AUS10 ideal for:

  • Busy home kitchens
  • Families
  • Users transitioning from Western knives

Which Steel Is More Durable?

In real-world use:

  • AUS10 is more forgiving
  • VG10 rewards good technique but punishes abuse

Corrosion Resistance

Both steels are stainless and perform very well here.

VG10 Corrosion Resistance

VG10 has:

  • High chromium content
  • Excellent rust resistance

It tolerates:

  • Moist kitchens
  • Acidic foods
  • Less-than-perfect drying habits

AUS10 Corrosion Resistance

AUS10 is also:

  • Highly corrosion resistant
  • Easy to care for

In practical terms:

  • Both steels are excellent
  • Neither requires obsessive maintenance

Sharpening: VG10 vs AUS10

Ease of Sharpening

This is where many users notice a big difference.

Sharpening VG10

  • Harder steel
  • Takes more time on stones
  • Requires consistent technique
  • Burr formation can be subtle

VG10 rewards patience and precision.

Sharpening AUS10

  • Softer and tougher
  • Burr forms easily
  • Faster sharpening sessions
  • Very forgiving on stones

For many users, AUS10 is simply more enjoyable to sharpen.

Which Steel Is Better for Beginners?

  • AUS10 is easier to sharpen
  • VG10 requires more skill

If you’re new to whetstones, AUS10 is often the better choice.

Cutting Feel & Feedback

Steel affects not just performance—but feel.

VG10 Cutting Feel

  • Crisp
  • Clean
  • Surgical

VG10 excels at:

  • Fine vegetable prep
  • Thin slicing
  • Precision cuts

AUS10 Cutting Feel

  • Slightly toothy
  • Confident
  • Robust

AUS10 feels great when:

  • Cutting dense foods
  • Working quickly
  • Doing high-volume prep

Neither feel is “better”—they’re simply different.

Blade Geometry Matters More Than Steel

It’s critical to say this clearly:

A well-designed AUS10 knife can outperform a poorly designed VG10 knife.

Geometry determines:

  • Cutting resistance
  • Food release
  • Safety
  • Fatigue

Steel supports performance—but geometry creates it.

This is why brands that focus only on steel names often disappoint.
