Choosing the right material for knives, tools, or CNC machined parts can be confusing. Many steels offer strength, but not all balance durability, sharpness, and corrosion resistance. This challenge often leads to costly mistakes. VG10 stainless steel solves this by combining hardness, toughness, and resistance—making it a trusted choice in CNC machining and knife-making.
VG10 stainless steel is a high-quality Japanese steel known for its hardness, corrosion resistance, and excellent edge retention. It is widely used in knives, tools, and CNC machined parts, offering a perfect balance of strength and durability. This makes VG10 steel an ideal choice for projects requiring precision and long-lasting performance.
Now that you know why VG10 stainless steel stands out, let’s dive deeper into its definition, properties, and applications to help you decide if it’s right for your project.
VG10 stainless steel is a premium Japanese steel developed by Takefu Special Steel Co., Ltd. The “VG” stands for V Gold, highlighting its “gold standard” quality in cutlery and precision machining. As a high-carbon stainless steel, it contains chromium, molybdenum, cobalt, and vanadium—elements that enhance hardness, wear resistance, and corrosion protection.
This steel is widely used in knives, tools, and CNC machined parts because it balances durability, edge sharpness, and machinability. Its reputation as a versatile VG10 steel grade makes it a preferred material in both the cutlery industry and CNC machining services.
VG10 stainless steel is often compared to other premium knife and tooling steels. In performance, it is close to 440C stainless steel in hardness and corrosion resistance but offers better toughness and edge retention. Compared to ATS-34 or 154CM, VG10 provides similar wear resistance while being easier to sharpen.
In CNC machining, VG10 is considered a mid- to high-end stainless steel grade, offering machinability similar to AUS-10 but with improved strength and durability. This makes it suitable for VG10 steel custom parts where precision and long-term performance are required.
Yes, VG10 stainless steel is highly suitable for knives. It was originally designed for Japanese cutlery and quickly became popular worldwide. Its high carbon content ensures excellent edge retention, while chromium and vanadium provide superior corrosion resistance and toughness. This makes it ideal for chef knives, pocket knives, and outdoor blades.
Knife makers prefer VG10 steel grade because it sharpens easily compared to ultra-hard steels, yet maintains a fine edge for a long time. Users benefit from a blade that resists rust, stays sharp through heavy use, and is easier to maintain.
VG10 stainless steel is a high-carbon, high-performance alloy known for its balance of hardness, toughness, and corrosion resistance. Its composition includes several alloying elements, each designed to enhance cutting performance, machinability, and durability. Below is the typical chemical composition of VG10 steel (MC66 specification):

Choosing the right steel depends on hardness, corrosion resistance, edge retention, and machinability. VG10 stainless steel often competes with other premium and mid-range steels in knives, tools, and CNC machined parts. Understanding how VG10 compares helps you select the optimal material for performance and cost efficiency.
VG10 Steel vs. 440C Steel
VG10 (59–61 HRC) is slightly harder than 440C (57–59 HRC), giving it superior edge retention. Both steels resist corrosion well, but VG10 performs better in acidic or high-moisture environments. 440C is easier to machine, making it suitable for budget-friendly knives or simpler CNC machined parts, whereas VG10 is preferred for high-end applications where long-term durability matters.
VG10 Steel vs. 154CM Steel
VG10 and 154CM have similar hardness (VG10 59–61 HRC, 154CM 58–60 HRC). VG10 has slightly better corrosion resistance, while 154CM offers higher wear resistance under extreme cutting conditions. VG10 is easier to sharpen, making it ideal for chef knives and precision CNC parts that require maintenance efficiency.
VG10 Steel vs. AUS-8 Steel
VG10 is harder (59–61 HRC vs. 56–58 HRC) and retains edges longer than AUS-8. While AUS-8 is more cost-effective and easier to sharpen, VG10 provides better corrosion resistance and durability, making it more suitable for premium knives, tools, and custom CNC components that see heavy use.
VG10 Steel vs. D2 Steel
D2 steel is slightly harder (60–62 HRC) and excels in wear resistance but is less corrosion-resistant than VG10. VG10 provides a better balance of toughness and rust resistance, while D2 is prone to staining without proper care. For applications requiring both corrosion resistance and edge retention, VG10 is generally preferred.
VG10 Stainless Steel vs. 316 Stainless Steel
316 stainless steel is highly corrosion-resistant, surpassing VG10 in resisting rust, but it is softer (55–58 HRC) and has lower edge retention. VG10 offers a sharper, longer-lasting cutting edge, making it the better choice for knives and wear-intensive CNC machined parts, while 316 is better for marine and chemical environments.
VG10 Steel vs. Carbon Steel
High-carbon steels have excellent hardness (58–62 HRC) and edge retention, comparable to VG10, but lack corrosion resistance. VG10 outperforms carbon steel in humid or wet conditions, reducing rust and maintenance. Carbon steel may be chosen for applications where sharpness is prioritized and rust prevention is manageable.
VG10 Steel vs. CPM S30V Steel
VG10 and CPM S30V have similar hardness (59–61 HRC) and edge retention. CPM S30V offers slightly higher wear resistance, but it is harder to machine and more expensive. VG10 balances performance, machinability, and cost, making it ideal for high-end knives and CNC machined parts where efficiency and long-term maintenance matter.

Proper care ensures that VG10 stainless steel retains its sharpness, corrosion resistance, and longevity—whether in knives, tools, or CNC machined parts. Despite its excellent properties, neglecting maintenance can reduce performance and lifespan.
1. Keep It Clean and Dry
After each use, wipe VG10 knives or tools with a soft cloth. Remove moisture, food residues, or debris immediately. For CNC machined parts, ensure surfaces are free from cutting fluids or corrosive chemicals.
2. Regular Sharpening
Maintain a sharp edge using a whetstone, honing rod, or professional sharpening service. VG10’s fine grain structure makes sharpening easier than super steels, but consistent care extends its edge retention.
3. Proper Storage
Store knives in a dry environment, ideally in knife blocks, sheaths, or protective sleeves. For CNC parts, use anti-corrosion sprays or keep them in controlled storage to prevent surface oxidation.
4. Avoid Harsh Chemicals
Do not use bleach, strong acids, or abrasive cleaners on VG10 stainless steel. These chemicals can damage the surface and reduce corrosion resistance.
5. Periodic Oil Application
For knives and tools, applying a thin layer of food-safe mineral oil helps prevent moisture-induced rust. For CNC components, use anti-corrosion oils to maintain the metal surface.
Choosing the right steel is crucial for the performance, durability, and cost-efficiency of your knives, tools, or CNC machined parts. VG10 stainless steel is an excellent choice when you need a balance of hardness, corrosion resistance, and edge retention.
