Kansept Symétrix K2141A4 CPM-S35VN Blade Blue-Purple Anodized Titanium Handle Frame Lock Folding Knife

The Kansept Symétrix K2141A4 embodies French knifemaker Alain André's philosophy of balanced symmetry. Its name, derived from the French word "symétrie," reflects the intentional mirrored lines running through both blade and handle, creating an ergonomic, centered grip perfect for everyday urban carry. Weighing just 2.56 ounces with a compact 2.85-inch blade, this lightweight folding knife excels for commuting and office-friendly EDC tasks. The CPM-S35VN stainless steel blade delivers superior edge retention and corrosion resistance, while its stonewashed finish adds tactical appeal. The blue-purple anodized titanium handle with swirl pattern provides both durability and aesthetic sophistication. A frame lock mechanism ensures secure deployment. Available with flat or sculpted swirl titanium handles, the Symétrix welcomes custom anodizing and laser engraving, allowing personalization for discerning collectors. This is thoughtful geometry transformed into functional precision.

CPM-S35VN Blade Introduction

CPM-S35VN is a premium powder-metallurgy stainless steel engineered for superior edge retention and excellent corrosion resistance, owing to its refined carbide structure and niobium additions. It offers enhanced toughness and ease of sharpening compared to S30V, yet it may exhibit slightly reduced wear resistance in demanding abrasive tasks. This balanced alloy demands professional sharpening equipment for optimal edge refinement.

SPECIFICATIONS

Kansept Symétrix K2141A4 - Product Overview

The Kansept Symétrix K2141A4 is a compact French-designed folder built around symmetry. Knifemaker Alain André shaped mirrored blade-and-handle lines so the knife sits naturally in either hand, and the Blue-Purple Anodized Titanium with Swirl Pattern titanium frame carries a large decorative disc pivot that anchors the whole design. The 2.85 in CPM-S35VN clip point blade is flat ground to stonewashed finish at 58-60 HRC, holding a keen edge through months of daily cutting. At 2.56 oz it disappears in the pocket, yet the full titanium frame gives it the rigidity of knives twice the price. If you want a refined frame lock EDC knife that reads as design object first and tool second, this is it.

CPM-S35VN Steel Selling Points

CPM-S35VN is Crucible's powder-metallurgy refinement of S30V, with niobium added to form finer, more uniform carbides. The practical result for an EDC user: the edge rolls less and micro-chips less than S30V, corrosion resistance stays excellent, and the fine carbide structure takes a very sharp, polished edge. At 58-60 HRC the Symétrix blade balances edge retention with real toughness for box cutting, package tape, cord and food prep. It is a premium steel that rewards a strop more than a heavy sharpening session.

Frequently Asked Questions

Is the Symétrix a good first premium knife?
Yes. The frame lock is intuitive, the blade is low maintenance stainless steel, and the size is legal-friendly in most jurisdictions.

Can the titanium be anodized or engraved?
Yes - the flat titanium scales are designed for custom anodizing and laser engraving, so colors and markings can be added without coatings.

How does CPM-S35VN compare to S30V?
S35VN adds niobium for finer carbides: better toughness and slightly easier sharpening at nearly the same edge retention and corrosion resistance.

Is it left-hand friendly?
The mirrored, symmetrical handle suits either hand. The pocket clip orientation is fixed, but grip and operation are ambidextrous.

What is the blade hardness?
58-60 HRC - a balanced heat treat that favors toughness and ease of sharpening over maximum edge retention.

CPM-S35VN Compared to Other Premium Steels

Ratings are relative within this class of steel, not absolute. Hardness varies by maker and heat-treat protocol.

Glossary of Terms

CPM-S35VN
Crucible powder-metallurgy stainless steel (1.4% C, 3% V, 0.5% Nb). Fine carbides give very good edge retention, very good corrosion resistance and better toughness than S30V.

Frame Lock
A locking system where a section of the handle frame itself springs against the blade tang. Strong, few parts, easy to operate one-handed.

Clip Point
A blade profile with a concave spine drop near the tip - a sharp, controllable point with plenty of belly for slicing.

Stonewash Finish
A tumbling finish that gives the steel a matte, scratch-hiding surface and reduces the visibility of edge wear.

Anodized Titanium
Titanium whose surface color is changed electrochemically without coatings - the color layer is part of the metal, so it cannot peel.

Disc Pivot
The large decorative pivot disc on the Symétrix, machined with a radial pattern; it stiffens the handle and defines the knife's look.

Care & Maintenance

1. Rinse the blade with warm water after cutting acidic or salty food, then dry it fully.
2. Wipe the stonewashed blade with a light oil (mineral or knife oil) if the knife will sit unused for weeks.
3. Do not machine-wash or dishwasher-clean the knife - detergents attack the titanium finish.
4. Keep grit out of the pivot: blow compressed air around the disc pivot after beach or dust exposure.
5. A drop of lubricant on the pivot every few months keeps the action smooth.
6. Check the frame lock engagement visually after any hard use before folding it away.
7. Strop the edge on loaded leather to refresh it; CPM-S35VN rarely needs a full reprofile.
8. Store the knife dry and open the lock when in long-term storage to unload the lockbar.
9. Anodized color is part of the metal - clean with a damp cloth, never with abrasive pads.
