What Is CPM S30V Steel? The Basics

CPM S30V is a martensitic stainless steel made using Crucible’s Crucible Particle Metallurgy (CPM) process, which ensures a fine, uniform grain structure for superior performance. Introduced in the early 2000s, it was designed specifically for knives, blending high hardness with excellent corrosion resistance. Its composition includes: Carbon (1.45%) for hardness and edge retention; Chromium (14.00%) for corrosion resistance (making it fully stainless); Vanadium (4.00%) for wear resistance via vanadium carbides; and Molybdenum (2.00%) for added strength. Typically hardened to 58-61 HRC, CPM S30V offers a sweet spot between toughness, sharpness, and ease of maintenance—making it a favorite for EDC, outdoor, and kitchen knives.

CPM S30V Steel Performance: Pros and Cons

So, what does CPM S30V bring to the table? Let’s evaluate its key attributes.

Edge Retention: Sharp for the Long Haul

CPM S30V excels at holding an edge. The vanadium carbides in its structure give it better wear resistance than traditional stainless steels like 440C or AUS-8. Whether you’re slicing through rope, filleting fish, or prepping veggies, this steel stays sharp longer than most mid-tier options. It doesn’t quite match super steels like S90V or K390 (see our for more on that), but for most users, it’s more than sufficient.

Corrosion Resistance: Stainless and Reliable

With 14% chromium, CPM S30V is highly corrosion-resistant. You can use it in wet environments—think fishing trips or humid kitchens—without worrying about rust. A quick rinse and dry are usually all it needs, making it lower maintenance than non-stainless steels like D2 or 1095.

Toughness: Durable but Not Indestructible

CPM S30V offers good toughness for a stainless steel, resisting chips and cracks under moderate use. It’s not as tough as carbon steels like CPM-3V, so avoid heavy prying or batoning. For slicing and general-purpose tasks, though, it holds up beautifully.

Ease of Sharpening: User-Friendly

Unlike harder steels (e.g., K390 or S110V), CPM S30V is relatively easy to sharpen. A standard ceramic stone or guided sharpening system will restore its edge without much hassle. This balance of edge retention and sharpenability is a big reason it’s so popular—unlike K390, which requires diamond stones (more on that ).

Wear Resistance: Built to Endure

Thanks to its vanadium content, CPM S30V has solid wear resistance, outpacing steels like 154CM or VG-10. It won’t wear down quickly, even with frequent use, making it a reliable choice for long-term performance.

CPM S30V vs. Other Steels: How It Stacks Up

Here’s how CPM S30V compares to other popular steels: CPM S30V vs. D2—S30V offers better corrosion resistance and edge retention, while D2 is tougher and cheaper; CPM S30V vs. 14C28N—S30V has superior edge retention, but 14C28N is easier to sharpen and more affordable; CPM S30V vs. S35VN—S35VN (its successor) adds toughness and ease of sharpening, but S30V remains a cost-effective classic; CPM S30V vs. K390—K390 beats it in edge retention and wear resistance but lacks corrosion resistance (see our ). For a well-rounded steel that’s hard to beat, S30V holds its own.

Is CPM S30V Steel Good for Knives?

Yes—CPM S30V is a phenomenal knife steel for anyone seeking a versatile, high-performing blade. It’s perfect for: EDC—Reliable for daily carry; Outdoor Use—Great for camping or fishing; Kitchen Knives—Sharp and low-maintenance. If you want a super steel with extreme edge retention (e.g., S110V or K390), look elsewhere—but for most users, S30V hits the sweet spot.

Caring for Your CPM S30V Knife

Keep your S30V blade in top shape with these tips: 1) Clean It—Rinse and dry after use, especially with acidic foods; 2) Sharpen It—Use a medium-grit stone or system like the Lansky for quick touch-ups; 3) Store It—A dry environment prevents any rare corrosion risks.

Final Verdict: Should You Buy a CPM S30V Knife?

CPM S30V steel is a benchmark for a reason: it combines sharpness, durability, and corrosion resistance in a way few steels can match. The Benchmade Tagout 533BK-05 is an excellent entry point—light, tough, and built to last. Want to compare it to another premium steel? Our dives into a non-stainless alternative.
