Features exceptionally high corrosion resistance and long edge retention. One of the best tool steels in the world today. It achieves a hardness of 57-60 HRC. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.
Blade - extremely sharp with a Drop Point profile, 2.5 mm thickness with a clearly marked belly blade. The blade was finished with a masking fine scratches, a non-reflective Stone Washed coating. Smooth blade (Plain type) was made with a full flat cut (Full Flat grind) which ensures durability, excellent cutting edge geometry and extreme cutting performance. Robust blade blockade mechanism - Liner-Lock.
Handle - stainless steel liners and technopolymer grip cladding (reinforced nylon) provide lightness and structural strength. Open construction, so-called „open-backed” simplifies cleaning and maintenance. A solid metal left / right-handed clip (deep-pocket metal clip) allows you to carry the knife deeply in your pocket (discreetly) in the tip-up position (tip top). In the rear part of the linings, an oval hole (lanyard hole) for a cable.
Technopolymer - also called the metal's successor. Modern material with a high percentage of glass fibers related to the polymer base and the presence (or not) of aramid (synthetic fibers, including Kevlar). It is characterized by unusual mechanical and thermal parameters. Advantages: corrosion-resistant, low weight, no maintenance (low coefficient of friction), electrical insulation (prevents the transmission of electricity), no reaction to the magnetic field, any color.
