In the world of everyday carry (EDC) tools, blade steel often dictates the entire user experience. While enthusiasts endlessly debate the merits of American super-steels and Japanese powder metallurgy, European knife manufacturers have quietly rallied around a different champion—a material that refuses to fit neatly into either the "budget" or "super-steel" category. That steel is N690, the Austrian workhorse that has become the backbone of elite Italian knife making and beyond.
If you're searching for the best N690 steel folding knives under $300 to add to your EDC rotation, this comprehensive guide is for you. We'll explore what makes this cobalt-enriched stainless steel so balanced and practical, compare it to other popular blade steels, and highlight five outstanding folding knives from five different brands that showcase this remarkable material.
What Is N690 Steel?
N690 (often labeled N690Co) is a high-performance martensitic chromium stainless steel produced by Austria's Böhler-Uddeholm. It is manufactured using electro-slag remelting (ESR) technology, which enhances purity and ensures a uniform, fine-grained microstructure.
What distinguishes N690 from many stainless steels is the addition of 1.5% cobalt. Cobalt strengthens the steel's matrix and improves its ability to retain hardness at elevated temperatures. The typical composition includes approximately 1.07% carbon, 17.3% chromium, 1.1% molybdenum, and 0.1% vanadium, along with the signature cobalt addition.
When properly heat treated, N690 achieves a working hardness of 58–62 HRC, with the optimal range for knife blades falling between 60 and 61 HRC. This hardness level strikes an excellent balance between edge retention and ease of sharpening.
The Performance Advantage
-
Excellent Corrosion Resistance: With over 17% chromium, N690 offers outstanding protection against rust and staining. It is "practically maintenance free" and particularly well-suited for humid climates, marine environments, and use around water.
-
Good Edge Retention: The combination of carbon, chromium, and vanadium forms hard carbides that resist abrasion and keep the blade sharp through extended use. N690 sits at a pleasing hardness to ensure satisfying edge retention.
-
Exceptional Ease of Sharpening: Perhaps N690's greatest user-facing strength is how easy it is to maintain. Many users consider it "easier to sharpen razor sharp than M390 while still having good edge retention". It takes a keen edge with basic ceramic stones and responds beautifully to stropping.
-
Balanced Toughness: N690 offers sufficient toughness for everyday tasks, with good resistance to chipping and rolled edges.
The Crucial Trade-Off: N690 is not an extreme steel. It doesn't hold an edge as long as M390 or S110V, and it isn't as tough as tool steels like 3V or Cru-Wear. What it offers instead is a remarkably practical balance—and perhaps most importantly, it's a joy to maintain. A steel that's easy to touch up is often more useful than one that holds an edge forever but is a nightmare to sharpen when it finally dulls.
N690 vs. Other Popular EDC Steels
N690 vs. VG-10: VG-10 is the classic Japanese stainless steel known for taking a razor-sharp edge. N690 is often called the "Austrian VG-10" because the two share a similar balance of properties. N690 and VG-10 are almost identical in composition, with N690 offering tighter tolerances and significantly higher chromium content for improved corrosion resistance. For EDC use, both are excellent, but N690 pulls ahead for users who want more consistent edge longevity.
N690 vs. D2: D2 is a classic tool steel known for good edge retention, but it is not stainless and will rust if neglected. N690 offers dramatically better corrosion resistance while being much easier to sharpen. D2 requires diligent oiling and maintenance; N690 does not.
N690 vs. 154CM: Both are mid-tier stainless steels with similar carbon content. N690 has a slight advantage in corrosion resistance due to its higher chromium content (17.3% vs. 14%) and is easier to sharpen, making it more user-friendly for maintenance.
N690 vs. M390: M390 offers elite edge retention and superior wear resistance. However, M390 is significantly more difficult to sharpen and comes at a higher price. Choose M390 if maximum edge retention is your priority; choose N690 if you want a balanced, easy-to-maintain EDC tool.

Caring for Your N690 Folding Knife
One of N690's greatest strengths is its low-maintenance nature. With over 17% chromium, it offers excellent corrosion resistance that makes it suitable for humid climates, marine environments, and everyday carry without constant worry. After use, simply wipe the blade clean with a soft cloth. A light coat of mineral oil applied to the pivot area will ensure smooth operation.
When it's time to sharpen, N690 is a pleasure to work with. Unlike high-carbide super-steels that demand diamond stones and significant patience, N690 sharpens quickly and easily with basic ceramic stones. Many users find that regular stropping between uses is sufficient to maintain peak sharpness and extend the time between full sharpening sessions.
Why Choose N690 for Your Next Folding Knife?
N690 steel represents the triumph of practical, balanced performance over exotic specifications. It doesn't chase the highest edge retention numbers or the most extreme hardness values. Instead, it delivers a carefully engineered combination of good edge retention, exceptional corrosion resistance, and—most importantly—effortless maintainability. For EDC enthusiasts who actually use their tools daily and want a blade that's easy to keep sharp without specialized equipment, N690 is a smart, practical choice.
The five folding knives highlighted above—the Kizer Justice, the Bestech Ornetta, the GiantMouse ACE Clyde, the Fox Knives Radius, and the MKM Isonzo—each represent a different brand and design philosophy.
