Cavy Yellow Ultem, Stonewashed, push dagger designed by the renowned MUZI Design studio, a perfect example of precision craftsmanship and functionality. The full tang construction provides exceptional durability, making it a reliable tool in a variety of situations. The blade is made of Sandvik 14C28N stainless steel, which is characterized by excellent corrosion resistance and long-lasting sharpness. The handle made of Ultem™ composite offers a secure and comfortable grip, even in difficult conditions. The textured surface provides additional control during use. The Kydex sheath is designed for practicality, and the simple clip allows for easy attachment to a belt or pocket edge, ensuring quick access to the knife. The whole combines elegant design with reliable functionality, meeting the expectations of even the most demanding users.

A push dagger, also known as a punch dagger, punch knife, push knife or, less commonly, push dirk, is a knife with a short blade and a T-shaped handle positioned at right angles to the blade. It is designed to be gripped and held in a closed fist so that the blade protrudes from the front of the fist, between the index and middle fingers or between the two middle fingers when the handle and blade are symmetrical.

14C28N - martensitic stainless chromium steel is the latest development in the range of knife steels produced by the Swedish steelworks Sandvik. The optimized chemical composition with 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 nitrogen to 0.11% (N), the corrosion resistance has been significantly increased. Considered an improved version of 13C26. Unbeatable in terms of price/quality!

Vacuum & Cryogenic - 14C28N steel undergoes a specialized heat treatment process involving two key stages. Vacuum Heat Treatment - the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the strength and structural integrity of the steel. Cryogenic Treatment After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation changes the residual austenite into martensite, significantly increasing the hardness, wear resistance and overall durability. Thanks to these advanced processes, 14C28N steel ensures exceptional performance, offering both razor-sharp edge retention and extraordinary blade durability.

Blade - Spear Point Double Edge, sharpened on both sides. Finished with a Stonewashed coating to hide fine scratches caused by use. Both cutting edges with a slightly marked belly converge towards the sharp tip of the blade. The thickness of the blade and the centrally placed grain ensure high durability, while the full flat grind provides excellent cutting edge geometry and extreme cutting performance. The finger ring additionally stabilizes the handle and prevents the knife from accidentally falling out of the hand.

ULTEM™ - a material belonging to the polyetherimide family, or simply PEI. This material is characterized primarily by high mechanical and impact strength with a very high strength-to-weight ratio. It is also characterized by high thermal resistance (180⁰C) and high chemical resistance to all kinds of solvents (synthetic and natural), greases and other chemicals. Add to this its complete insensitivity to weather conditions, and you get the perfect material for knife handles.

Handle - grips made of transparent Ultem™, a virtually indestructible material that is insensitive to weather conditions, resistant to chemicals and mechanical damage, textured to improve grip. The contoured shape ensures a comfortable, secure grip even with wet hands. The finger cut-out at the front and the thumb ramp improve the grip.

Sheath - made of kydex, extendable, protects the blade. Thanks to the clip attached to it, the knife can be attached to a belt or equipment in almost any way.
