Civivi Vyrent Knife Black G10, Black Stonewashed Nitro-X7 (C25037-1)

Civivi Vyrent Black G10, Black Stonewashed Nitro-X7 – EDC folding knife with Liner Lock

The Civivi Vyrent Black G10, Black Stonewashed Nitro-X7 folding knife (C25037-1) is a full-size EDC folder that combines a Nitro-X7 steel blade with a contoured G10 handle. The blade can be opened using the flipper or the ambidextrous thumb stud, and ceramic ball bearings ensure smooth operation of the mechanism.

The 88.40 mm blade features a Drop Point profile, a flat grind, and a black stonewashed finish. The Liner Lock mechanism works in conjunction with steel liners, and the reversible clip allows the knife to be carried on the right or left side in a tip-up configuration.

Nitro-X7 60–62 HRC and flat grind

The blade is made of Nitro-X7 steel, hardened to 60–62 HRC. The flat grind provides a versatile geometry suitable for everyday cutting tasks, while the Drop Point profile offers a well-controlled tip and a long cutting edge.

Black stonewashed finish

The black stonewashed finish gives the blade a subdued, technical look and pairs well with the black grips and liners. The uniform color scheme emphasizes the utilitarian nature of the C25037-1 variant.

Contoured G10 handle and two opening mechanisms

The handle is made of black G10 and contoured for a more secure grip. The knife can be opened using a flipper or a thumb stud, and steel spacer sleeves create an open handle design. The Liner Lock secures the blade in the open position.

Technical Data

Frequently Asked Questions

How do I care for Nitro-X7 steel?

After use, clean the blade and dry it thoroughly. Regularly removing moisture and dirt helps keep the surface and edge in good condition.

How do I sharpen a Drop Point blade?

Maintain a consistent angle along the entire length of the edge and guide the blade evenly across the abrasive material. Near the tip, reduce the pressure to preserve its original geometry.

How does the Liner Lock work?

When opened, a spring-loaded steel liner slides behind the base of the blade and holds it in the open position. Pushing the liner back allows you to close the knife safely.

How do you clean a G10 handle?

The handle can be cleaned with a soft brush or a damp cloth, then thoroughly dried. Pay special attention to the contoured recesses on the surface.

How do you maintain ceramic ball bearings?

The area around the axle should be periodically cleaned of dust and debris. If necessary, apply a small amount of a light lubricant designed for folding knife mechanisms.
