Choosing the right blade steel for an everyday carry folder defines how often you will need to sharpen it, how well it resists rust, and how much abuse the edge can handle. The Kansept Fenrir, designed by custom maker Greg Schob of Sparrow Knife Co. and manufactured by Kansept, leverages CPM-S35VN as its core workhorse steel.
Developed by Crucible Industries specifically for premium cutlery, CPM-S35VN remains one of the most balanced alloys in modern knife production. Here is everything you need to know about how this steel performs on the Fenrir platform.
Metallurgy and Performance Specs
CPM-S35VN is a American-made martensitic stainless steel produced using powder metallurgy. Crucible engineered S35VN by taking the proven CPM-S30V formula and adding 0.5% niobium. The addition of niobium creates fine niobium carbides, which improve grain structure and increase toughness without reducing wear resistance.
| Steel Characteristic | Rating / Value | Real-World EDC Impact |
| Target Hardness | 59 - 61 HRC | Holds an edge through tough tasks while remaining easy to resharpen |
| Corrosion Resistance | High (14% Chromium) | Resists staining from sweat, rain, fruit acids, and daily moisture |
| Edge Retention | Very High | Slices through cardboard, tape, and rope for weeks before dulling |
| Toughness | Excellent | Resists micro-chipping when hitting hard inclusions like staples |
| Sharpening Difficulty | Moderate | Touches up quickly on standard ceramic, diamond, or leather strops |
S35VN vs. Other Fenrir Steel Options
To understand why CPM-S35VN is often considered the ideal all-around choice for daily carry, it helps to compare it against the other steel options available in the Fenrir lineup:
Compared to CPM-20CV
While CPM-20CV offers ultimate wear resistance for pure abrasive slicing, its higher carbide volume makes it more prone to micro-chipping under impact and noticeably harder to sharpen. S35VN strikes a friendlier balance between edge holding and ease of maintenance.
Compared to Damascus
The Damascus variants offer striking visual flair for collectors, but S35VN provides superior overall corrosion resistance and consistent homogeneous edge stability for hard daily utility work.
Synergy with Harpoon Drop Point Geometry
On the Fenrir, S35VN steel is ground into a wide harpoon drop point profile with a hollow primary grind. This combination delivers exceptional slicing performance:
-
Thin Behind the Edge: The hollow grind creates a keen slicing profile that glides through dense material without binding.
-
Resilient Apex: The added niobium content in S35VN prevents the delicate apex of the hollow-ground edge from rolling or chipping during lateral pressure.
-
Controlled Downforce: The harpoon thumb ramp allows you to apply heavy downforce directly over the blade belly without straining the steel.
Mechanical Support Across Lock Variants
A high-performance steel requires a rock-solid locking mechanism to handle heavy push cuts safely. The S35VN Fenrir platform accommodates several lock configurations depending on your preference:
-
Frame Lock: Pairs S35VN with a rigid titanium frame bar for maximum structural integrity.
-
Crossbar Lock: Delivers smooth, ambidextrous deployment using dual thumb studs.
-
Liner Lock: Provides classic, lightweight internal lockup for easy pocket transport.
-
Top Liner Lock: Features a top-mounted release along the spine so your fingers stay safe when closing the blade.
Is the S35VN Fenrir Right for You?
If you want a dependable, high-end EDC knife that delivers exceptional slicing performance, resists corrosion in harsh environments, and can be easily maintained at home with basic sharpening tools, the CPM-S35VN Kansept Fenrir is arguably the most versatile configuration in the entire series.
