AR-RPM9: The innovative steel grade from ArtisanCutlery

The world of knife making is a constant balancing act between innovation and tradition. One of the latest achievements that is attracting attention is AR-RPM9 steel, a proprietary development by ArtisanCutlery. This type of steel offers an impressive combination of performance, cost-benefit ratio and technological sophistication. But what makes this steel so special?

What is AR-RPM9?

AR-RPM9 is a powder metallurgy steel specifically designed for use in high-quality, yet affordable knives. Powder metallurgy (PM) is an advanced manufacturing process in which steel is processed in a fine powder form and bonded together under high pressure and temperatures. This process provides a uniform structure and improved material properties.

The steel was developed in collaboration with ArtisanCutlery to bridge the gap between traditional, easily accessible steels like 8Cr13MoV and expensive premium steels like S35VN.

Chemical composition

The composition of AR-RPM9 is carefully balanced to optimize corrosion resistance, hardness and cutting ability. Here are the essential elements:

  • Chromium (Cr): 18% – Gives the steel its rust-proof properties.
  • Carbon (C): 0.93% – Provides hardness and wear resistance.
  • Vanadium (V): 1% – Increases abrasion resistance and improves fine grain.
  • Molybdenum (Mo): 0.45% – Promotes corrosion resistance and high temperature strength.
  • Manganese (Mn): 0.4% – Supports hardenability and strength.

The high concentration of chromium and vanadium ensures exceptional cutting ability and corrosion resistance, while powder metallurgy creates a fine and uniform microstructure.

Advantages of AR-RPM9

  1. Excellent cutting performance:
    Thanks to the fine grain and high-quality alloy, AR-RPM9 offers excellent edge retention. This means less frequent resharpening, even with intensive use.

  2. Corrosion resistance:
    With a chromium content of 18%, the steel is excellently protected against rust, making it ideal for outdoor knives and everyday carry knives (EDC).

  3. Hardness and toughness:
    The steel typically reaches a hardness of around 59-61 HRC. This hardness offers an ideal balance between robustness and the ability to hold a sharp edge.

  4. Affordability:
    Compared to other powder metallurgy steels, AR-RPM9 offers an impressive price-performance ratio. This makes it accessible to knife enthusiasts without compromising on quality.

areas of application

AR-RPM9 is used primarily in EDC (Everyday Carry) knives , where durability, reliability and corrosion resistance are critical. ArtisanCutlery uses the steel in a variety of models, including:

  • ArtisanCutlery Centros: An elegant folding knife with modern aesthetics.
  • CJRB Feldspar: A budget-friendly knife that perfectly demonstrates the advantages of AR-RPM9.
  • CJRB Ria: A lightweight and slim design for everyday use.

Thanks to its versatility, AR-RPM9 is also suitable for outdoor, survival and kitchen knives.

Conclusion

With AR-RPM9, ArtisanCutlery has launched a type of steel that sets new standards in the knife world. By combining modern powder metallurgy, a well-thought-out chemical composition and an attractive price, this steel offers exceptional performance for all types of applications.

Whether you are a seasoned knife enthusiast or a casual user who values ​​quality, the AR-RPM9 is an exciting choice that shows how innovation and affordability can go hand in hand in knife making.
