1.4116S STEEL BLADE

The knife features a blade with a classic working profile and a flat grind, making it highly versatile in use. The blade is made from 1.4116S stainless tool steel, offering very good corrosion resistance and good wear resistance.

This steel should not be confused with the popular 1.4116 (X50CrMoV15). The steel used in this model contains alloying elements such as vanadium, molybdenum, and nitrogen, allowing it to reach a hardness of 59–61 HRC after heat treatment. In practice, it offers properties comparable to the popular stainless steel Sandvik 14C28N.

The high grind and thin cutting edge ensure excellent cutting performance while remaining easy to resharpen.

The full-tang construction means the knife is made from a single piece of steel running through the entire length and width of the handle, significantly increasing its strength.

AVAILABLE BLADE FINISHES

Satin finish
A blade finish with characteristic lines running in one direction. It gives the blade an elegant, technical look and highlights the geometry.

Stonewash
A finish designed for users who use their knives intensively. The surface effectively masks signs of wear and minor scratches formed during use.

Each finish may naturally wear over time depending on usage intensity and type of work performed.

HANDLE

The handle is built in a full-tang construction, significantly increasing the overall strength of the knife.

The handle scales are made from synthetic laminates available in two variants:

• G10 – a black fiberglass composite resistant to moisture, temperature changes, and most chemicals.
• Micarta – a brown composite valued for its natural texture and excellent grip, especially during outdoor use.

The scales are secured to the knife with stainless steel screws, ensuring durability and stability during intensive use.

SHEATH

The knife is available with two sheath options:

Leather sheath
Handcrafted from natural brown leather. Decorated with stitching and reinforced with brass rivets, ensuring durability and a classic look. Allows comfortable vertical belt carry.

Kydex sheath
A durable sheath made from ABS material (Kydex type), equipped with a steel clip for vertical belt carry.
