Best N690 Steel Fixed Blade Knives Under $300

In the world of knife steels, certain materials achieve legendary status through sheer performance in the field. N690—a high-carbon, cobalt-enhanced martensitic stainless steel developed by the Austrian manufacturer Böhler-Uddeholm—is one such alloy. It occupies a sweet spot that many knife enthusiasts and professionals prize: exceptional corrosion resistance, solid edge retention, and a level of toughness that inspires confidence when the work gets demanding. Whether you're building a versatile EDC rotation, equipping your pack with dependable tools for the trail, or searching for a blade that thrives in humid or marine environments, understanding what makes N690 special is the first step to making a confident choice.

In this guide, we'll explore the metallurgy and characteristics of N690 steel, compare it to other popular blade materials, and showcase five of the best N690 fixed blade knives under $300 that put this remarkable material to work.

What Is N690 Steel?

N690 is a high-performance martensitic stainless steel produced by Böhler-Uddeholm in Austria. It contains approximately 1.07% carbon, 17.3% chromium, 1.5% cobalt, 1.1% molybdenum, and 0.1% vanadium. The high chromium content provides outstanding corrosion resistance, while the addition of cobalt acts as a secondary hardening element, helping carbides distribute more uniformly and boosting hardness without making the steel brittle. Molybdenum and vanadium further enhance wear resistance and edge retention.

Key performance characteristics include:

• Excellent Corrosion Resistance: With approximately 17.3% chromium, N690 offers exceptional resistance to rust and staining, making it ideal for humid climates and marine applications【2†L5-L8】.

• Solid Edge Retention: N690 typically achieves 58–60 HRC, which provides satisfying edge retention for everyday and outdoor use.

• High Toughness: N690 produces an overall strong blade with high impact resistance, resisting chipping when cutting dense materials【3†L8-L12】.

• Ease of Sharpening: Despite its respectable hardness, N690 is relatively easy to sharpen and takes a keen edge without excessive effort.

How N690 Compares to Other Popular Knife Steels

N690 vs. VG-10

This is the most direct comparison. VG-10 has slightly higher hardness and better edge retention, while N690 is tougher, more corrosion-resistant, and easier to sharpen. Both are premium steels; choose N690 for better durability and lower maintenance.

N690 vs. 440C

N690 is comparable to 440C in performance and value, with keen edge qualities and excellent corrosion resistance. N690 is tougher than 440C and offers improved wear resistance due to the addition of vanadium.

N690 vs. D2

This comparison highlights two different design philosophies. D2 is a high-carbon tool steel with excellent wear resistance, but it has poor corrosion resistance and requires regular maintenance. D2 matches N690 in wear resistance but has far worse corrosion resistance—N690 is better for wet or humid environments.

N690 vs. CPM-S30V / CPM-S35VN

S30V and S35VN are premium powder metallurgy steels that offer better edge retention than N690, but they are significantly more expensive and harder to sharpen. N690 offers comparable toughness, dramatically better corrosion resistance than S30V, and is much easier to maintain.
