14C28N

Overview

Sandvik developed 14C28N as a nitrogen-alloyed stainless steel in the 12C27 family. It combines toughness and corrosion resistance with easy sharpening, which explains its popularity in production knives.

The “N” stands for nitrogen. Adding it helps the steel reach useful hardness while keeping carbide volume modest. That combination allows 14C28N to resist corrosion and chipping without becoming difficult to sharpen.

In the knife market, 14C28N is commonly used in budget and mid-price knives because it balances corrosion resistance, toughness, and sharpenability without requiring premium pricing.

Composition and History

The typical chemical composition of 14C28N is:

• Carbon (0.62%) provides moderate carbon content for hardness.
• Chromium (14%) provides stainless behavior and corrosion resistance.
• Nitrogen (0.11%) supports hardness and corrosion resistance while keeping carbide volume low.
• Manganese (0.6%) aids hardenability.
• Silicon (0.2%) helps with processing.
• Plus trace amounts of phosphorus and sulfur

In many steels, more wear resistance comes from more carbon and more carbides. That can help edge retention, but it often makes sharpening harder and toughness lower. 14C28N takes a different route: moderate carbon, good chromium, and a small nitrogen addition.

This is why 14C28N is called a “nitrogen steel” or “nitro steel.” The term refers to nitrogen alloyed into the steel, not nitriding, which is a surface treatment.

That chemistry gives 14C28N four useful traits:

• Can reach useful knife hardness without excessive carbide volume
• Offers high toughness for a stainless steel
• Has strong corrosion resistance for wet, humid, and food-prep use
• Responds well to simple sharpening equipment

Sandvik developed 14C28N as an improvement over 12C27. It fits the same general family of fine-grained stainless steels associated with easy sharpening, good toughness, and practical corrosion resistance rather than maximum wear resistance.

Performance Tradeoffs

Edge retention

14C28N has good edge retention, but edge holding is not its headline feature. S30V, M390, and other higher-carbide steels will usually cut abrasive material longer. 14C28N earns its place by being easier to sharpen and tougher than many steels in the same price range.

Knife Steel Nerds testing places 14C28N below many premium wear-resistant steels for edge retention, as its composition suggests. The buying decision comes down to whether easier maintenance and better toughness are worth more frequent sharpening.

For EDC, it handles packaging, food, cord, and normal daily cutting. It also works well in camping, hunting, fishing, and home kitchen knives. It usually outperforms basic budget steels but trails premium wear-resistant steels. Touch-ups are quick, and a simple stone or guided sharpener is usually enough.

Toughness

Toughness is one of 14C28N’s strongest traits. Its low carbide volume helps it resist chipping better than many stainless steels that chase higher wear resistance.

Toughness testing often places 14C28N near the better stainless options in this category. In practice, this means:

• Thin edges can work well: Supports slicier geometry better than many budget stainless steels
• Better chip resistance: Useful for outdoor, work, and utility knives
• Predictable behavior: Usually rolls or dulls before it chips badly, depending on heat treatment and edge geometry
• Field use: Tolerates normal working-knife abuse better than many stainless alternatives

For budget knives that see real use, this toughness gives useful margin. It does not make the knife indestructible, but it makes 14C28N a forgiving choice.

That toughness suits:

• Outdoor and bushcraft applications
• Hunting and fishing (impact resistance, thin blade stability)
• EDC knives that may see rough utility cutting
• Kitchen work where thin edges and easy maintenance matter

Corrosion resistance

14C28N offers excellent corrosion resistance for a knife steel in its price range. The chromium content provides the stainless baseline, and the nitrogen addition helps keep more chromium available for corrosion resistance rather than tied up in carbides.

It performs well in pocket, kitchen, and outdoor use without demanding constant attention. Humid, wet, and coastal conditions are reasonable, and normal washing and drying are enough after contact with food acids. Its corrosion resistance is better than AEB-L and most budget steels.

The corrosion resistance makes 14C28N well suited to:

• Fishing knives (moisture, salt spray)
• Outdoor knives (rain, humidity, neglect)
• Kitchen cutlery (food acids, frequent washing)
• EDC folders (pocket carry moisture, perspiration)

Basic drying after use and reasonable storage are enough for most owners. It is much less fussy than semi-stainless steels like D2, though saltwater and wet storage can still cause problems if ignored.

Ease of sharpening

14C28N is easy to sharpen compared with most modern premium knife steels. The low carbide volume and moderate hardness help it respond quickly to common stones.

It forms a burr quickly, takes an edge without much trouble, and is easier to deburr than many higher-carbide steels. Water stones, ceramic stones, diamond stones, guided systems, and field stones all work. Touch-ups are quick, and full resharpening is straightforward.

This is especially useful for newer knife owners. A steel that is easy to sharpen teaches good maintenance habits instead of making sharpening feel like a chore.

That gives owners several workable options:

• Touch up an edge during lunch break with a pocket stone
• Restore a dull edge with basic bench stones
• Use toothy or polished edges depending on the job
• Maintain the knife without specialty abrasives

For working knives, that ease of maintenance can matter more than a small edge-retention gain.

Historical context and market position

14C28N was introduced in the late 2000s and became strongly associated with Kershaw and other value-focused production knives. It filled a useful gap: better performance than basic stainless steels while staying affordable enough for mass-market knives.

No single test number explains its appeal. Manufacturers got a steel that sharpens easily, resists rust, and handles rougher use better than many low-cost alternatives.

Kershaw used it in popular models such as the Blur and Leek, and the steel later became more common across budget and mid-price knives from several brands.

Easy sharpening and basic corrosion care make it convenient for a working knife.

Best Use Cases

Budget EDC folders

14C28N is common in affordable EDC folders:

• Kershaw (Blur, Leek, Link, numerous models)
• CRKT (various budget lines)
• Ruike and other value-focused brands

Outdoor and bushcraft knives

The toughness and corrosion resistance make 14C28N popular for:

• Fixed blade outdoor knives

• Bushcraft applications
• Hunting and fishing knives

Kitchen knives

Its corrosion resistance and easy sharpening suit:

• Home kitchen cutlery

• 14C28N generally has better corrosion resistance
• Both offer excellent toughness and easy sharpening
• Similar edge retention
• 14C28N often appears in lower-priced production knives

Compared to 12C27:

• 14C28N is the improved version
• Usually better hardness potential and corrosion resistance
• Can achieve higher hardness
• Similar toughness
• 14C28N is often chosen when corrosion resistance and easy sharpening are prioritized

Compared to 420HC:

• Usually better edge retention
• Often better toughness
• Similar or better corrosion resistance
• Similar ease of sharpening
• 14C28N is generally stronger in edge retention and toughness when quality-control consistency is comparable

Compared to premium steels (S30V, VG-10):

• Often better toughness than higher-wear stainless steels
• Strong corrosion resistance
• Easier to sharpen
• Lower cost
• Better value for users who prioritize maintenance and toughness over maximum edge holding

Conclusion

14C28N is a practical steel for buyers who want a knife that is easy to own. It resists corrosion well, sharpens quickly, and has enough toughness for real working use.

Its main compromise is edge retention. If you spend a lot of time cutting cardboard, rope, carpet, or other abrasive material, a higher-wear steel may be worth paying for. For a pocket knife, kitchen utility knife, fishing knife, or outdoor knife that is simple to maintain, 14C28N is hard to fault.

Check the grind and heat treatment before buying. A well-made 14C28N knife offers useful toughness and corrosion resistance at an accessible price.
