Knife Steel Guide: A Brief List of Steels and What They Are

With складные ножи becoming more common in our daily lives, understanding knife steels is crucial. The type of steel in a blade can greatly affect how it performs. Enthusiasts and pros alike need to know about different steel types used in knives and how they’re used.

Knowing Your Steel

Blades play a crucial role in our daily lives, aiding with tasks at home and in high-stakes situations.

A knife’s performance, influenced by the steel used, reflects both functionality and the art of craftsmanship and material science.

The Crucial Properties of Steel

Several characteristics define the potential of a steel blade. Here, we lay the groundwork by exploring the pivotal properties:

Hardness (HRC): Refers to the steel’s resistance to deformation, which is measured on the Rockwell Hardness Scale (HRC). A high HRC value indicates that the steel can maintain a sharp edge for an extended period, enhancing its durability. However, with increased hardness, there is a trade-off as it may become more susceptible to brittleness, impacting its overall toughness and resilience.
Toughness: This is the impressive capacity of a material to soak up energy without breaking. Tough steel, recognized for its durability, can endure heavy use without breaking or chipping, making it a dependable option for different applications.
Износостойкость: Measures the steel’s resistance to abrasion to ensure the blade’s edge stays sharp even with prolonged use. This test evaluates steel durability for long-lasting performance.
Устойчивость к коррозии: Steel’s rust resistance is vital for its durability and effectiveness, especially in humid or corrosive settings. This quality helps the steel uphold its structure long-term, making it a reliable option for various uses.

The Stainless Versus Carbon Dilemma

Before getting into details, it’s crucial to distinguish between the two primary types of steel utilized for knife blades.

Углеродистая сталь

Carbon Steel is like a trusty cast iron skillet – it gets better with time if you take care of it. It’s a favorite for many knife enthusiasts because it can get super sharp and keep that edge for a long while, making your cutting precise and effortless.

Just like a skillet, it’s not fond of water; if you don’t keep it dry, it can rust. This means after you use your carbon steel knife, give it a quick wipe-down to keep it in tip-top shape. It’s a bit old-school, but many swear by its reliability and straightforward maintenance.

Simple Tips for Carbon Steel: Keep it dry, sharpen it occasionally, and it’ll be one of your most reliable tools.

Examples of carbon steels are 1095, and CPM-3V.

The 1095 is known for its toughness and high carbon content, making it ideal for heavy-duty cutting tasks. CPM-3V, a modern powdered steel, is highly sought after for its exceptional wear resistance and edge retention.

Нержавеющая сталь

Stainless steel knives are the reliable raincoats of the knife world. They keep rust away just like a raincoat keeps the rain off. This is great if you prefer low maintenance. While they may not stay as sharp as carbon steel knives, they are sharp enough for most tasks and easier to maintain.

Steel made simple: Think of stainless steel as your go-to knife for everyday tasks – it’s hardy, doesn’t need a lot of pampering, and won’t wear out its welcome by rusting.

440C: Think of 440C like the dependable family car – it’s not the flashiest but gets the job done reliably. It’s one of the most popular kinds of stainless steel used for knives because it’s a good all-rounder. It strikes a nice balance between being hard enough to keep an edge and not so hard that it’s tough to sharpen. Plus, it resists rust well, so it’s perfect for your regular kitchen chores or as a companion on camping trips.
ВГ-10: VG-10 is a high-tech sports car of steel – it’s more upscale, hails from Japan, and provides a level of sophistication in its performance. It’s particularly well-known for having a great edge – sharp and durable. That’s why you’ll often see it in the hands of sushi chefs who demand perfection. VG-10 is also rust-resistant, which is perfect for humid kitchens or outdoor activities near water.
