Why N690 Keeps Showing Up in EDC Knives
Some blade steels get famous. Others quietly do the job for years and only stand out when you compare spec sheets side by side and notice that a $39 knife is running the same blade material as a $130 one. Bohler N690 lives in that second category.
N690 shows up across the EDCDeal catalog on Kizer's value line, on CIVIVI fixed blades, on Vosteed's aluminum-handled folders and on Artisan Cutlery frame locks. It is cobalt-alloyed, it is fully stainless, it is genuinely easy to sharpen, and it is almost never the reason a knife disappoints its owner. If you have been wondering whether N690 is still "good enough" in 2026, or whether you should hold out for S35VN, this guide covers the chemistry, the honest trade-offs, and the best N690 knives currently in stock.
What Is N690 Steel?
N690 is a martensitic stainless steel produced by Bohler-Uddeholm in Austria, which today sits inside voestalpine High Performance Metals. It was developed for industrial cutting applications - food processing blades, cutting tools, and equipment that has to survive moisture and repeated sharpening - rather than for the knife market specifically. Knife makers adopted it because it delivers a hard, stain-resistant edge without the brittleness of very high-carbon tool steels.
The headline ingredient is cobalt. In Bohler's published composition, N690 carries roughly 1.07% carbon, 17.3% chromium, 1.5% cobalt, 1.1% molybdenum and 1.1% vanadium. That puts it in the same broad family as VG-10, but with a noticeably higher chromium content - one reason it keeps turning up on knives meant to be used around water, sweat, fertilizer and food.
Reading the Chemistry
Four elements do most of the work in N690:
- Carbon (1.07%) sets the ceiling on hardness. At this level N690 can be taken into the 58-60 HRC range that Kizer publishes for models like the Barbosa, which is where a stainless EDC steel performs best.
- Chromium (17.3%) is what makes the steel "stainless" in the practical sense. Chromium forms a passive oxide layer on the surface (how stainless steel passivates), and the more chromium that stays in solution rather than locking up in carbides, the better the steel resists rust.
- Cobalt (1.5%) is the signature of N690 and of VG-10. Cobalt does not form carbides; it raises the temperature at which the steel can be tempered, which helps the maker hold hardness and keeps the edge from softening quickly in use.
- Vanadium (1.1%) forms small, extremely hard carbides that resist the edge rolling over during slicing. Kept modest, as it is here, vanadium contributes wear resistance without turning the steel into a sharpening headache.
The practical result is a fine-grained steel. Fine grain is exactly what you want if you like thin, low-angle edges, because the steel can support a keener geometry without chipping out under normal cutting loads. If you want the longer version of how alloying elements interact, our knife steel alloying elements explainer walks through carbon, chromium, vanadium and molybdenum one at a time.
What N690 Does Well
Corrosion resistance that outclasses budget tool steels
At 17.3% chromium, N690 is meaningfully more stainless than the D2 and 1095 that dominate budget knives, and it carries more chromium than 154CM (about 14%) or VG-10 (about 15%). More free chromium generally means more resistance to surface staining when the blade is sweated on, rained on, or used to break down fruit and vegetables. It is not in the same league as nitrogen steels like LC200N or Vanax, but for a knife that lives in a pocket in a humid climate, it is comfortably in the "wipe it down and you are fine" bracket.
Edge holding that matches the price tag
N690 holds a working edge about as well as you would expect from a mid-range stainless in the VG-10 / 154CM class. It will not compete with CPM S35VN or M390 on pure wear resistance, because those steels carry far more vanadium carbide. The trade-off runs the other way too: N690 gets sharp quickly and gets sharp again with a few passes on a strop, which matters more to most people than extending a dull edge for one extra week. Our steel ranking breakdown covers where N690 sits relative to the premium carbides.
Toughened, stable edges
Because N690 keeps carbide volume moderate and grain size small, it tolerates thin edge geometry well. If you sharpen at 15-17 degrees per side rather than the factory 20, you get a noticeably more aggressive slicer without the edge crumbling. That relationship between edge thickness and cutting performance is covered in detail in our edge geometry guide.
Easy maintenance
Fine carbides plus high chromium means N690 responds to simple sharpening gear. A basic guided system, a medium water stone or even a ceramic rod will bring it back. Diamond abrasives are optional rather than mandatory, which is not something you can say for S90V or Maxamet. If you are still deciding on angles, start with our guide to the best sharpening angle for EDC knives.
Where N690 Falls Short
Three honest limitations:
- Wear resistance is mid-tier. N690 is not a carbide monster. Edge retention trails S35VN, S45VN, Elmax and M390, and there is a large gap to S90V. Knife Steel Nerds maintains a steel ratings database if you want the comparative charts. If you cut a lot of abrasive material - cardboard all day, for example - the premium vanadium steels pull ahead. Compare S45VN vs S35VN or the 14C28N vs Nitro-V vs S35VN face-off to see how the tiers separate.
- It is usually run at 58-60 HRC, not 61+. Makers heat treat N690 for toughness and ease of grinding, which is sensible for a production knife but leaves some edge retention on the table compared with a harder premium steel.
- Corrosion resistance has a ceiling. It is stainless, not salt-proof. Left wet with fertilizer, plant sap or seawater on the blade, any stainless will eventually show spots.
N690 vs 14C28N vs VG-10 vs 154CM
| Steel | Carbon | Chromium | Typical HRC | Character |
|---|---|---|---|---|
| N690 | ~1.07% | ~17.3% | 58-60 | Cobalt-alloyed stainless, strong stain resistance, fine grain, easy to sharpen |
| 14C28N | ~0.62% | ~14.0% | 58-60 | Lower carbon, very tough, superb corrosion resistance, takes a razor edge fast |
| VG-10 | ~1.0% | ~15.0% | 59-61 | Cobalt-alloyed, popular in Japanese production knives, balanced all-rounder |
| 154CM | ~1.05% | ~14.0% | 58-61 | Molybdenum-heavy American stainless, good wear resistance, less stain resistant than N690 |
Read the table as a map rather than a scoreboard. N690 and VG-10 are cousins. 14C28N trades some wear resistance for toughness and corrosion resistance. 154CM leans toward wear resistance at the cost of some stain resistance. None of them is "better" in the abstract.

Getting the Most Out of an N690 Blade
Sharpen it thinner than the factory edge. N690's fine grain supports 15-17 degrees per side for a pocketknife. You give up a little edge stability and gain a lot of cutting aggression.
Strop instead of re-sharpening. Because the steel takes a keen edge easily, most maintenance is 20-30 passes on a strop with compound rather than a full session on stones.
Dry it after wet jobs. Garden work, kitchen prep and rainy hikes all leave residue. Rinse, dry and you will never see a spot. If you do find rust, our rust removal and prevention guide covers fixes for every steel family.
Match the edge finish to the job. A toothier edge off a coarse stone cuts fibrous material better; a polished edge suits push cuts and food. N690 takes both without complaint.
FAQ
Is N690 a good knife steel? Yes. N690 is a solid mid-range stainless with excellent corrosion resistance, fine grain and easy sharpening. It sits below premium vanadium steels like S35VN and M390 on wear resistance but above typical budget steels like 8Cr13MoV and D2 in stain resistance.
Is N690 better than VG-10? They are close cousins - both cobalt-alloyed stainless steels. N690 carries more chromium (about 17.3% versus about 15%), which favors stain resistance, while VG-10 is often run slightly harder. Pick based on the specific knife and heat treatment rather than the name.
Is N690 better than 14C28N? They solve different problems. 14C28N is tougher and more corrosion resistant with lower carbon; N690 has more carbon and holds a working edge longer. For thin, hard-use edges 14C28N is often the safer choice; for general daily cutting N690 is the better all-rounder.
Can N690 rust? It can, though it is far more resistant than D2 or carbon steels. Leaving fertilizer, sap or saltwater on the blade for extended periods will eventually cause spotting. Rinse and dry after wet or dirty jobs.
How hard is N690 usually heat treated? Most production knives run N690 between 58 and 60 HRC - Kizer publishes that range for models such as the Barbosa. That range balances edge retention against toughness and grindability.
The Short Version
N690 is not the steel you buy to win a spec-sheet argument. It is the steel you buy when you want a stainless blade that sharpens easily, shrugs off humidity, supports a thin edge and costs less than the premium carbides. In 2026 that makes it the default choice in the $35 to $80 bracket, and a perfectly sensible one well past $100 - especially in the Vosteed Morel, CIVIVI Keen Nadder and CIVIVI Midwatch fixed blade.
