At A Glance
D2, an air-hardened tool steel, stands out for its hardness and corrosion resistance. It retains its edge for a significant period but can be more brittle under strenuous use. Sharpening D2 can be challenging, and it’s best suited for heavy-duty tasks. VG10, a high-end Japanese stainless steel, is popular for its excellent edge retention, sharpness, and impressive corrosion resistance. It offers a balance between hardness and brittleness, being less likely to chip under heavy-duty use. VG10 is easier to sharpen and is ideal for demanding conditions.

VG10 Steel
D2 Steel
Blade steel is an indispensable attribute to evaluate when purchasing a knife. D2 and VG10 are two popular blade steels that are often juxtaposed. This article seeks to embark on an exhaustive analysis, exploring the intricacies of these two renowned knife steel types, D2 and VG10.
The comparison will span their composition, hardness, toughness, corrosion resistance, edge retention, and ease of sharpening. This assessment aims to discern which of the two, D2 or VG10, stands as the superior choice for blade steel.
Entering the intricate labyrinth of knife-making materials can be a daunting task, even for the experienced, and seemingly overwhelming for novices.
Steels Background
Before we immerse ourselves in the comparison, let’s take a moment to comprehend each type of steel.
D2
D2 is an air-hardened tool steel that is high in carbon and chromium, commonly referred to as “semi-stainless,” as it falls just shy of the required amount of chromium (13%) to be designated as full stainless steel. It’s heralded for its high hardness and admirable corrosion resistance. D2 has been a stalwart in the knife-making industry, earning the favor of both custom knife makers and large production firms.
VG10
VG10, or V Gold 10, is a high-end Japanese stainless steel that is incredibly popular for kitchen cutlery and outdoor knives. The ‘G’ in VG stands for ‘Gold’ which refers to the ‘gold standard’ that this level of stainless steel is considered to have met. VG10 is recognized for its excellent edge retention and sharpness, alongside impressive corrosion resistance.
Steel Composition
Our comparison commences with the chemical composition of each steel.
D2
- Carbon: 1.5%
- Chromium: 12%
- Molybdenum: 1%
- Vanadium: 1%
- Manganese: .6%
- Silicon: .6%
- Iron: Balance
VG10
- Carbon: 1.0%
- Chromium: 15%
- Molybdenum: 1.0%
- Vanadium: 0.2%
- Manganese: 0.5%
- Phosphorus: 0.03%
- Silicon: 0.5%
From the above compositions, D2 exhibits higher Carbon content, while VG10 has more Chromium, offering higher corrosion resistance.
D2 vs VG10 – Complete Comparison
Hardness
Hardness is a crucial property of knife steel, dictating the edge retention and wear resistance.
D2 boasts a Rockwell hardness (HRC) of 55-62, signifying a very hard steel. It’s highly wear-resistant and retains an edge for a significant period. Nevertheless, its hardness makes it more brittle than VG10, potentially leading to chipping under strenuous use.
VG10 typically attains an HRC of 58-61, proving to be hard enough to ensure excellent edge retention, yet not as brittle as D2.
Toughness
Toughness in steel pertains to its ability to withstand chips and cracks.
While D2 is reasonably tough, its brittleness can render it susceptible to chipping under heavy-duty usage.
VG10, on the other hand, is known for its commendable toughness, making it a popular choice for kitchen cutlery and outdoor knives that undergo rigorous use.
Corrosion Resistance
Corrosion resistance assesses a steel’s resilience against rust and oxidation.
D2, with its 12% Chromium content, provides respectable corrosion resistance, although it demands regular care to stave off rust.
VG10, with 15% Chromium, is exceptionally resistant to corrosion, which is one of its standout features. It’s ideal for knives subjected to moist or humid conditions.
Ease of Sharpening
Ease of Sharpening signifies how easy the steel is to sharpen with normal methods. It usually correlates inversely with edge retention and hardness.
Sharpening D2 can be a tad challenging due to its high carbon and chromium content. However, when employed with the right techniques, a razor-sharp edge can be achieved.
VG10, while offering excellent edge retention, is relatively easier to sharpen, making it an appealing choice for those who require regular honing of their knives.
Edge Retention
Edge retention is the capacity of a steel to retain its sharpness during use.
D2 delivers outstanding edge retention owing to its hardness, making it a suitable candidate for tasks that involve heavy cutting or chopping.
VG10 is also celebrated for its remarkable edge retention. It strikes an impressive balance between maintaining sharpness and resilience against chipping or cracking.
Price
D2 is generally more affordable than VG10, making it an excellent choice for those seeking a balance between performance and cost.
VG10, being a premium-grade steel, commands a higher price, justified by its superior corrosion resistance, edge retention, and overall performance.
Conclusion
In the final analysis, both D2 and VG10 present themselves as exceptional blade steels, each boasting unique strengths. D2 is a highly wear-resistant steel with good corrosion resistance and excellent edge retention, although its hardness can make it prone to chipping and somewhat difficult to sharpen. It’s best suited for heavy-duty tasks where less frequent sharpening is preferable.
On the contrary, VG10 exhibits outstanding edge retention and corrosion resistance, while also being relatively easier to sharpen. It’s an ideal choice for those seeking a premium knife steel for use in demanding conditions and doesn’t mind paying a bit more for these superior properties.
The choice between D2 and VG10 ultimately rests on the intended use of the knife and personal preference. Both steels have proven their mettle in knife making. It’s essential to consider the reputation of the brand or manufacturer when purchasing a knife to ensure high quality and proper heat treatment of the blade steel.
