Guide To The Best Knife Steel

The world of steel extends well past the well-known carbon and stainless steel classifications, and picking the type of steel for your knife boils down to your preference and what you plan to do with your knife. 

Knife Steel Types: Comparing Their Properties, Uses, And Price

From Damasus Steel to Tool Steels to Premium and Low-End Steels, there are a seemingly infinite number of knife steel types. Like different toppings on a pizza, each has distinct properties, uses, and price tags. 

From the affordable 420 stainless steel to the top-shelf VG-10, understanding the unique properties of each steel can help you identify a likely price and its ideal use.

How Much Does The Steel Of A Knife Matter

The quality of a knife's steel is paramount. Everything from balance, sharpness, and longevity are all impacted by the steel of the knife. 

What’s The Difference Between Carbon And Stainless Steel And Some Stuff In Between

Carbon and stainless steel are perhaps the two most well-known steel names. 

Stainless Steel contains a high chromium count (over 15%) and offers unmatched corrosion resistance. This blend of iron and chromium mineral composition creates a distinctive shininess.

Carbon Steel is an alloy of iron, carbon, and chromium (in lower counts than stainless steel) and is the preferred choice for many professional chefs and knife enthusiasts. It can be forged thinner and sharper than stainless steel, translating into a significantly more precise cut.

What Are Steel Standards

Steel standards, alternatively referred to as steel grades, offer a framework for categorizing, assessing, and determining the unique properties of various types of steel. The standards include composition, physical traits, thermal characteristics, and other metallurgical aspects. Steel standards define all carbon, structural, stainless, ferritic, austenitic, and alloy variations.

These standardized guidelines assist metallurgical labs and refineries to ensure they use premium steel in their products.

What Is Rockwell Hardness

Simply put, The Rockwell Hardness Scale measures how resistant a material is to permanent indentation - a higher number means harder steel. Harder steels can retain a sharp edge for longer, but it becomes more brittle. 

Knives are measured for their hardness on the Rockwell scale through a two-step process. Essentially, the procedure involves applying a small preliminary force, known as a minor load, and then an additional force, known as a major load.

  1. A minor load is first applied to the knife's blade using a diamond cone (for harder materials) or steel ball indenter (for softer materials). This establishes the zero point on the scale.
  2. Then, a major load is applied. Once this major load is removed, maintaining the minor load allows a deep permanent impression on the material.

The depth of penetration from the zero point up to this indented mark determines the Rockwell hardness number. A lower penetration signifies a higher Rockwell number and hence, indicates a harder material.

Average Rockwell Hardness By Knife Type

The hardness of a blade varies depending on its purpose. Axes, for example, have an HRC of 40-50, while an ultra-sharp chef's knife is around 55-60 HRC.

What Is Powder Steel

Powder steel, or Powder metallurgy, is a process of producing metal components by heating and refining alloys into a metallic powder. The powder is blended with other metals to achieve the desired material properties and characteristics for a particular steel. 

The Five Key Properties Of Knife Steel

With so many types of steel on the market, how do the experts know which one to use for kitchen knives? Well, they often rate them on the following five properties.


Hardness is the bedrock of a kitchen knife's performance - the harder the steel, the sharper the edge, making it scythe through ingredients effortlessly.


Toughness shields your knives from chipping and breaking. While you want a thin and sharp blade, you don’t want something flimsy and susceptible to cracking.

Wear Resistance

A good knife should last a long time. Therefore, knife makers value steel that remains sleek and sturdy for years.

Corrosion Resistance

Corrosion and oxidization will naturally occur in carbon blades. Exceptional steel offers a degree of corrosion resistance without sacrificing sharpness.

Edge Retention

Edge retention is how long a knife can maintain its razor-sharp edge. When looking for kitchen knife steel, edge retention is the trait that separates your favorite chef knife from a dull butter spreader.

Heat Treatment

Heat treatment for steel involves heating and cooling the metal to change its physical properties, enhancing characteristics like hardness, toughness, strength, and resistance to wear. 


Finally, a highly-regarded type of steel will be easily sharpened using a whetstone, honing rod, or a sharpening block. Bonus points if it does not have to be sharpened often.

Common Knife Steel Types

We're cutting right to the chase and breaking down the most common types you'll find in the kitchen or your pocket. From the tough and sharp carbon steel to the shiny and strong stainless steel, and the fancy-looking Damascus with its cool patterns, each kind has its special features. Whether you're cooking dinner, going camping, or just need a handy tool, knowing about these steel types helps you pick the right knife for the job. Let's get started and find out what makes each knife steel tick!

Plain Carbon Steels

Plain Carbon steels are some of the most common knife steels in the world. Devoid of extravagant alloying elements, they consist of a minimum of 0.7% carbon, making them exceptionally sharp.


1075 steel offers excellent malleability for forging intricate shapes. It contains 0.75% carbon, which makes it stand on the balance beam between hardness and resilience flawlessly. Ideal for a bushcraft knife, its ability to withstand external forces is remarkable.


The 1084 steel is your sturdy old-school workhorse. Its composition with about 0.80-0.90% carbon ensures impressive hardness without compromising the necessary flexibility. It also possesses Iron, Manganese, Phosphorus, and Sulfur.

Alloy Steels

Alloy steel, a distinct type of steel, is composed of blending multiple elements with steel, referred to as 'alloying elements'. These elements bolster the steel's properties, providing more hardness, resilience, wear resistance, and toughness, resulting in a sturdier and more dynamic form of steel. 

Typically, these alloying elements make up less than 5% of the overall steel material.

Alloying Elements and Their Impact on Blades

The quality, durability, and performance of a blade are heavily influenced by the alloying elements present in its composition. Here are some common elements used in knife steel:

  1. Carbon: An essential component of steel, it increases sharpness and decreases the weight of the blade. However, higher carbon makes the steel more susceptible to corrosion.
  2. Chromium: Chromium enhances a blade's wear resistance, tensile strength, and toughness. It gives steel its stainless properties by forming a passive layer that prevents corrosion.
  3. Molybdenum: Another mineral used to bolster steel's resistance to both corrosion and brittleness at high temperatures, significantly enhancing toughness.
  4. Vanadium: This element refines the steel's grain structure to provide superior edge retention.
  5. Nickel: Nickel improves the overall strength and toughness of the blade. 

By understanding these elements' impacts on blades, crafters can adjust steel to achieve the perfect balance for specific uses. From kitchen knives to outdoor survival blades, these small elemental changes can make all the difference in performance.

Tool Steels

Tool steels are a category of carbon and alloy steels recognized for their hardness, abrasion resistance, and ability to hold a cutting edge at high or cool temperatures.
