In the ever-evolving world of premium knife steels, one name has consistently stood at the forefront of balanced performance: CPM-S35VN. Developed as a direct evolution of the iconic S30V, this powder metallurgy stainless steel has become a cornerstone of modern everyday carry (EDC), favored by both elite custom knifemakers and the world‘s leading production brands. It’s not the absolute best at any single attribute—and that‘s precisely its strength. S35VN represents the goldilocks of super steels: tough enough, wear-resistant enough, stainless enough, and user-friendly enough to satisfy nearly every knife enthusiast.
If you’re searching for the best CPM-S35VN steel folding knives to elevate your pocket tools, this comprehensive guide is for you. We‘ll explore what makes S35VN so exceptional, compare it to other premium blade steels, and highlight five outstanding folding knives from five different brands that showcase this legendary material at its finest.
What Is CPM-S35VN Steel?
CPM-S35VN is a martensitic stainless tool steel produced by Crucible Industries using their proprietary Crucible Particle Metallurgy (CPM) process. Released in 2009 as an upgrade to the wildly popular CPM-S30V, it was developed in collaboration with custom knifemaker Chris Reeve to address specific feedback from the knife community regarding toughness and machinability.
The secret to S35VN‘s refined performance lies in its chemistry and manufacturing process. The CPM process atomizes molten steel into a fine powder, which is then sintered to create a billet with an extremely fine, uniform carbide distribution. This ensures consistent performance and edge stability throughout the blade.
The alloy’s composition was strategically rebalanced from S30V. The vanadium content was reduced from 4% to 3%, and crucially, 0.5% niobium was introduced. This substitution is key: niobium forms very fine, hard carbides that refine the steel‘s microstructure. The result is a blade steel that delivers approximately 15-20% greater toughness than its predecessor without any loss of wear resistance. It also offers improved resistance to edge chipping and is notably easier to machine and polish during manufacturing—which translates to better factory edges and smoother action for the end user.
Why CPM-S35VN Excels in EDC Folding Knives
S35VN has earned its reputation because it delivers where it counts for daily pocket tools:
-
Balanced Toughness: The addition of niobium makes S35VN significantly more resistant to chipping and rolling than S30V, a critical advantage for EDC tasks that might involve incidental contact with staples, hard materials, or accidental drops.
-
Excellent Edge Retention: While the wear resistance is nearly identical to S30V, the improved toughness allows for more stable edges at acute sharpening angles. You get a blade that stays sharp for a long time but won‘t microchip during hard use.
-
Strong Corrosion Resistance: With approximately 14% chromium, S35VN is a true stainless steel that resists rust and staining in humid environments, making it ideal for year-round carry.
-
User-Friendly Sharpening: Perhaps most importantly for long-term ownership, S35VN is easier to sharpen than many other “super steels” like M390 or S110V. It responds well to diamond and ceramic stones, making maintenance manageable for enthusiasts without requiring specialized equipment.
Typical Hardness: Most major knife manufacturers harden CPM-S35VN to the 59–61 HRC range, which provides an optimal balance between edge retention and ease of sharpening.
CPM-S35VN vs. Other Premium Blade Steels
Understanding how S35VN stacks up against its peers will help you make an informed decision for your EDC tools.
CPM-S35VN vs. CPM-S30V
S35VN is the direct successor, and the improvement is tangible. It offers approximately 15-20% better toughness without any loss of edge retention, plus improved machinability. While S30V remains an excellent steel, S35VN is objectively the superior, more refined version. If you have a choice between two identical knife models, the S35VN variant is almost always the better buy.
CPM-S35VN vs. M390/CPM-20CV
M390 and its equivalents offer superior edge retention and corrosion resistance compared to S35VN, thanks to higher vanadium and chromium content. However, M390 is noticeably more difficult to sharpen and typically commands a higher price point. Choose M390 if you want the absolute longest edge life and are equipped with diamond stones; choose S35VN if you value a more balanced, user-friendly package that you can easily maintain yourself.
CPM-S35VN vs. CPM-154
CPM-154 is another powder metallurgy stainless steel that emphasizes toughness and ease of sharpening over raw edge retention. Compared to S35VN, CPM-154 is slightly tougher and even easier to sharpen, but it will not hold an edge as long. S35VN strikes a better balance for most EDC applications, offering meaningful improvements in wear resistance while still maintaining good toughness. Choose CPM-154 if ultimate sharpenability and a hand-rubbed finish appeal to you; choose S35VN for superior all-around performance.
CPM-S35VN vs. CPM-3V
CPM-3V is a tool steel, not a stainless steel, and it operates in a completely different performance category. It offers legendary impact toughness—far exceeding S35VN—making it ideal for fixed blades and hard-use folders. However, 3V has significantly lower corrosion resistance and will rust if neglected. S35VN is the better choice for low-maintenance EDC in varied environments; 3V is for those who prioritize maximum toughness and are willing to perform regular oiling and maintenance.
Five Exceptional CPM-S35VN Folding Knives Worth Your Consideration
Now, let‘s explore five outstanding folding knives from five different brands that showcase the incredible capabilities of CPM-S35VN.
1. Spyderco Native 5
The Spyderco Native 5 represents an evolution in American knifemaking and holds the distinction of being Spyderco’s first production folder made using Crucible Inc. powdered technology CPM-S35VN steel.

Caring for Your CPM-S35VN Folding Knife
One of S35VN‘s greatest strengths is its relatively low-maintenance nature. With 14% chromium, it offers true stainless properties that make it an ideal choice for daily carry without constant worry about rust. After use, especially when cutting acidic foods or working in humid conditions, simply wipe the blade clean with a soft cloth. A light coat of mineral oil applied to the blade and pivot area will ensure smooth operation and long-term corrosion protection.
Sharpening S35VN is manageable with proper equipment. While it offers far better edge retention than budget steels, it remains accessible to enthusiasts using diamond or ceramic stones. Unlike ultra-high-wear steels like S110V or M390, S35VN does not require specialized sharpening skills or excessive patience. Many users find that regular stropping with a diamond compound is sufficient to maintain peak sharpness between more thorough sharpening sessions.
Why Choose CPM-S35VN for Your Next Folding Knife?
CPM-S35VN steel represents a carefully engineered sweet spot in the world of premium blade materials. It doesn‘t force you to choose between edge retention and toughness, between performance and sharpenability. Instead, it delivers a refined, balanced package that works for everyone—from the seasoned collector to the dedicated daily user.
The five folding knives highlighted above—the Spyderco Native 5, the Benchmade Mini Bugout, the Zero Tolerance 0450CF, the Chris Reeve Large Sebenza 31, and the Toor Merchant 2.0—each represent a different brand and design philosophy, but they all share one thing in common: a blade crafted from the legendary CPM-S35VN. Whether you prioritize American-made precision, ultralight carry, premium materials, heirloom quality, or tactical durability, there’s a CPM-S35VN folder ready to become your trusted everyday companion. Choose one, maintain it with care, and experience firsthand why this steel remains the gold standard for premium EDC tools.
