Sleipner steel is considered a high-quality tool steel, developed by Bohler-Uddeholm in Austria. This steel is recognized for its exceptional blend of features, offering strong edge retention, impressive hardness, and excellent toughness. It is known to perform even better than the well-known D2 steel in many aspects.

Advantages of Sleipner as Knife Steel

Sleipner steel is characterized by its exceptional toughness and hardness. The composition of this steel provides excellent resistance to wear and chipping, making it ideal for heavy-duty tools. In everyday carry (EDC) knives, these properties ensure a reliable tool in tough conditions. Sleipner is often compared to D2 steel; however, it offers increased toughness, giving it a performance edge.

The steel is also easier to sharpen than others of similar hardness. This quality is appreciated by EDC knife enthusiasts as it allows for regular sharpening without much hassle.

Disadvantages of Sleipner for Knives

However, Sleipner steel has its drawbacks, particularly in corrosion resistance. It requires careful maintenance to avoid rusting. Additionally, given its premium status, Sleipner steel generally comes with a higher price tag, which may be a consideration for some users.

Is Sleipner Rust Resistant?

Despite its many strengths, Sleipner steel is not very rust-resistant. Owners of knives made from this steel should ensure they perform regular maintenance. Applying protective oils and cleaning the knives regularly will help mitigate corrosion and extend the lifespan of the blade.

How Durable is Sleipner?

The hardness of Sleipner steel is remarkable, with an HRC rating between 60-64. This high hardness contributes to exceptional edge retention, keeping the blade sharper for longer. This hardness also increases the overall strength of the blade, allowing it to effectively handle the rigors of everyday use.


Sleipner steel has developed a strong reputation for excellent performance in knife crafting. It is praised for its remarkable hardness and toughness, making it a preferred choice among high-end utility knives, everyday carry knives, and even hunting knives. Its reliability under intense conditions makes it a favored choice for many.
