14C28N - martensitic chromium stainless steel is the latest achievement in the range of knife steels produced by the Swedish steelworks Sandvik. Its optimized chemical composition, featuring a unique combination, ensures the highest quality, excellent edge performance, high hardness, and corrosion resistance. By reducing the carbon content to 0.62% (C) and increasing the chromium content to 14.0% (Cr), as well as adding 0.11% nitrogen (N), corrosion resistance has been significantly improved. Considered an improved version of 13C26 steel. Unbeatable in the price/quality category!

Vacuum & Cryogenic - 14C28N steel undergoes a specialized heat treatment process comprising two key stages. Vacuum Heat Treatment involves hardening the steel in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the steel’s strength and structural integrity. Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation converts residual austenite into martensite, significantly increasing hardness, wear resistance, and overall durability. Thanks to these advanced processes, 14C28N steel delivers exceptional performance, offering both razor-sharp edge retention and remarkable blade durability.Blackwashed - a blade finishing method that combines two techniques. Black Coating - a protective, non-reflective black coating. Stonewashed - after the coating is applied, the blade undergoes a process that gives it a slightly aged, satin-matte appearance and effectively masks minor scratches and marks caused by use. The final result is a unique, aged look with a matte, dark finish that is both stylish and practical. It is a more aesthetic variant of the classic black stonewashed.

Blade—a drop point profile has been used, offering an excellent balance between tip precision and the versatility of everyday cutting. The clearly defined spine supports smooth blade guidance, especially when cutting ropes, cardboard, tape, and other utility materials. This type of geometry also performs well in light outdoor tasks. The flat grind is responsible for the cutting properties, ensuring smooth entry of the blade into the material and good control during use. This solution maintains a balance between cutting aggressiveness and edge durability, which is crucial for an everyday-use knife. Additionally, jimping has been added to the spine to improve thumb control during more precise movements.

Handle - made of Micarta composite, a material valued for its durability, moisture resistance, and secure grip. The delicate texture improves hand grip, which works particularly well when working in more challenging conditions or with a damp grip. The grip profile maintains a slim, ergonomic shape with slightly rounded edges, ensuring the knife fits comfortably in the hand despite its compact size. The full tang construction running the entire length of the handle increases the knife’s overall rigidity and provides a sense of solidity. The knife is complemented by steel screws and a lanyard hole, enhancing its practicality for EDC and outdoor use. Another key component of the set is the Kydex sheath with a Tek-Lok attachment, which allows for convenient carrying on a belt, gear, or backpack, emphasizing the mobile nature of this model.
