Selecting the ideal steel for an everyday carry folder comes down to striking a fine balance between edge holding, toughness, corrosion resistance, and ease of sharpening. The Kansept Fenrir, designed by custom maker Greg Schob of Sparrow Knife Co. and manufactured by Kansept, reaches its ultimate utilitarian potential when equipped with CPM-S35VN blade steel.
Engineered specifically for cutlery applications, this powder metallurgy alloy transforms an already ergonomic design into an unyielding daily workhorse.

Metallurgy Built for Real-World Utility
Developed by Crucible Industries in collaboration with custom knifemakers, CPM-S35VN improves upon classic blade steels by introducing niobium to the chemical composition. This microscopic adjustment yields significant practical benefits for hard-working tools:
| Chemical / Physical Trait | Technical Value | Practical Workhorse Advantage |
| Niobium Additive | ~0.50% | Forms fine niobium carbides that improve grain structure and boost impact toughness |
| Chromium Content | 14.00% | Provides strong stain resistance against sweat, rain, fruit acids, and ambient humidity |
| Vanadium Content | 3.00% | Generates hard vanadium carbides to maintain long-lasting slicing edges |
| Optimal Hardness | 59 - 61 HRC | Delivers excellent wear resistance without making field sharpening overly difficult |
Practical Edge Retention and Impact Resilience
On a daily basis, an EDC knife encounters unpredictable cutting tasks—ranging from clean paper scoring to abrasive double-walled cardboard processing and wood carving.
Resistance to Chipping Under Load
Ultra-high-wear steels like CPM-20CV excel at prolonged abrasive slicing, but their higher carbide volume makes them more susceptible to micro-chipping when impacting hidden staples or dense knots. CPM-S35VN provides superior structural toughness, allowing the Fenrir’s thin-ground edge apex to absorb impacts without breaking down.
Straightforward Maintenance
When the edge eventually dulls after extended weeks of utility work, CPM-S35VN responds rapidly to standard abrasives. Unlike super-steels that require extended diamond-hone sessions, S35VN can be restored to a shaving-sharp edge using basic ceramic stones or a leather strop loaded with diamond paste.
Harmonizing Steel Performance with Blade Profile
The Fenrir’s broad harpoon drop point profile amplifies the natural strengths of CPM-S35VN steel.
-
Hollow-Ground Efficiency: The tall hollow grind thins the material behind the cutting edge, letting the carbide structure of S35VN slice through thick rope, hose, and packaging with minimal friction.
-
Harpoon Downforce: The forward thumb ramp allows you to apply heavy downward pressure directly over the blade belly, trusting the steel's toughness to handle high cutting loads safely.
-
Collector Versatility: While options like Damascus cater to visual flair, CPM-S35VN provides the raw performance required for true workhorse applications.
Structural Stability Across Locking Options
To support high-load utility cutting, the S35VN blade is paired with various heavy-duty lock configurations depending on your preference:
-
Frame Lock: Offers direct lockbar engagement against the blade tang for maximum rigidity.
-
Crossbar Lock: Enables fast, ambidextrous one-handed operation via dual thumb studs.
-
Liner Lock: Maintains a lightweight, clean internal structure for effortless pocket carry.
-
Top Liner Lock: Keeps the lock release along the top spine so your fingers stay clear of the edge during blade closure.
The Definitive Daily Companion
By pairing Greg Schob's custom ergonomics with Crucible's CPM-S35VN steel, the Kansept Fenrir earns its status as a top-tier daily workhorse. It combines edge holding, corrosion resistance, and impact toughness into a reliable cutting tool that stands up to demanding daily wear.
