Nitro X7 with a hardness of 61–62 HRC
Nitro X7 stainless steel provides good corrosion resistance, edge retention, and performance suitable for everyday use. A hardness of 61–62 HRC helps maintain sharpness when cutting cardboard, tape, cord, plastics, and other everyday materials.
Drop Point, Plain Edge, and Stonewashed
The Drop Point profile offers a functional tip and versatile geometry for cutting and precision work. The Plain Edge facilitates blade control, while the Stonewashed finish minimizes the appearance of fine scratches and signs of wear.
Black-Blue Carbon Fiber
Carbon Fiber grips are characterized by high rigidity and low weight. The black-and-blue layered pattern gives the handle a modern look, and the material’s moisture resistance makes it easy to keep the knife clean.

Frequently Asked Questions
How do I care for Nitro X7 steel?
After use, clean the blade of any dirt and dry it thoroughly. Regular care is especially important after contact with moisture, salt, food, or chemicals.
How do I sharpen a Nitro X7 steel blade?
You can use ceramic or diamond sharpening stones or a sharpening guide system. The most important thing is to maintain a consistent angle and guide the blade evenly along the entire length of the edge.
Is the Crossbar Lock suitable for left-handed users?
Yes. The lock pin is accessible from both sides of the handle, the double-sided pin allows you to open the knife with either your right or left hand, and the clip can be moved to the opposite side.
How do you clean the carbon fiber grips?
Wipe the carbon fiber with a soft cloth dampened with water and a mild detergent. Do not use harsh solvents or abrasive materials that could dull the surface.
How do you reposition the tip-up clip?
After unscrewing the screws, move the clip to the prepared mounting point on the other side of the Handle. Tighten the screws evenly, without using excessive force.
