When evaluating a modern folding knife, the synergy between blade steel choice and overall blade geometry determines its real-world performance. The Kansept Fenrir, born from a collaboration between Kansept and custom maker Greg Schob of Sparrow Knife Co., achieves an ideal sweet spot in its CPM-S35VN iteration.
Engineered by Crucible Industries specifically for high-end cutlery, CPM-S35VN remains a benchmark alloy in the EDC community. Here is an in-depth look at how this steel elevates the performance, edge retention, and daily usability of the Fenrir platform.
Technical Specifications and Chemical Composition
CPM-S35VN is a martensitic stainless steel designed to improve upon the toughness of its predecessor, CPM-S30V, without sacrificing wear resistance or corrosion protection. By introducing niobium carbides alongside vanadium and chromium, the steel achieves a finer grain structure.
| Property / Component | Specification / Value | Practical Benefit in Daily Use |
| Blade Steel | CPM-S35VN Powder Metallurgy | Fine, uniform carbide distribution for high edge stability |
| Hardness Rating | 59 - 61 HRC | Optimal balance of edge holding and ease of resharpening |
| Carbon (C) | 1.40% | High hardness potential and fundamental wear resistance |
| Chromium (Cr) | 14.00% | Exceptional stain and corrosion resistance in humid environments |
| Vanadium (V) | 3.00% | Forms hard vanadium carbides to extend slicing edge life |
| Niobium (Nb) | 0.50% | Enhances toughness and prevents micro-chipping under pressure |
Edge Retention and Real-World Cutting Performance
On the Fenrir, CPM-S35VN is paired with a broad harpoon drop point profile featuring a precision hollow grind. This thin geometry behind the edge allows the carbide-rich steel to slice through dense materials with minimal drag.
Wear Resistance in Repetitive Slicing
In daily cutting tasks—such as breaking down corrugated cardboard, slicing heavy rope, or stripping insulation—the high vanadium and niobium content helps the edge resist abrasive wear. The steel maintains its razor-sharp working edge through extended cutting sessions before requiring a strop or hone.
Resistance to Micro-Chipping
One of the key engineering advantages of S35VN over higher-vanadium steels like CPM-20CV is its superior impact toughness. When encountering accidental staples in boxes or knotty wood during outdoor carving, the fine grain structure resists micro-chipping along the apex, preserving the structural integrity of the edge.
Mechanical Integration Across Lock Options
The CPM-S35VN Fenrir models are offered in several handle configurations and lock styles, each providing a rock-solid platform for high-pressure cutting:
-
Frame Lock: Pairs the S35VN blade with a titanium lockbar for maximum rigidity during heavy push cuts.
-
Crossbar Lock: Offers smooth ambidextrous opening with dual thumb studs for rapid deployment.
-
Liner Lock: Delivers classic internal locking mechanics keeping the folder lightweight in pocket.
-
Top Liner Lock: Positions the release along the spine so your fingers stay clear of the CPM-S35VN edge during closure.
While exotic options like Damascus appeal to collectors, the S35VN variant remains the ultimate workhorse choice for users seeking a dependable, easy-to-maintain daily carry knife.
