Sencut Quirk Knife Black-Gray G10, Black D2 (S25099-2)

Sencut Quirk Black-Gray G10, Black D2 Folding Knife (S25099-2)

The Sencut Quirk S25099-2 is a manual EDC folder with a more subdued, dark aesthetic. The black Clip Point blade made of D2 steel is paired with a G10 handle in Black and Gray and black internal components.

The flipper and thumb stud provide two independent ways to open the knife manually, while ceramic ball bearings ensure smooth blade operation. Locking is provided by the proven Liner Lock mechanism.

D2 – High Abrasion Resistance

D2 steel, hardened to 59–61 HRC, holds its cutting edge well and is resistant to heavy wear. In practice, it performs well in regular EDC tasks such as cutting cardboard, plastics, cords, or packaging.

Clip Point with a black finish

The blade features a Clip Point profile, providing a functional tip and a versatile cutting edge. The flat grind promotes efficient cutting, and the black finish emphasizes the uniform, technical aesthetic of this variant.

Black-Gray G10 and Liner Lock

The G10 grips in Black and Gray create a handle that is resistant to moisture and daily wear and tear. The construction is supported by steel liners and black stainless steel spacers.

The Quirk can be opened manually using either the flipper or the thumb stud. Ceramic ball bearings reduce pivot resistance, while the Liner Lock stabilizes the blade when fully open. The ambidextrous tip-up clip allows you to switch the carrying side.

Technical Data

Frequently Asked Questions

Does D2 steel require corrosion protection?

Yes. D2 has higher corrosion resistance compared to many tool steels, but it should not be treated as typical stainless steel. After contact with moisture, it is advisable to clean the blade, dry it, and periodically treat it with a suitable protective agent.

How do you sharpen a flat Clip Point blade?

In practice, you can start with about 15–20° per side, maintaining the factory sharpening angle. Regular touch-ups are easier than fully restoring a heavily worn edge.

How does the Liner Lock work on the Quirk model?

When the blade is opened, a section of the steel liner slides under the blade’s base and prevents it from closing on its own. To release the mechanism, you must slide the liner to the side and close the blade in a controlled manner.

Is the Sencut Quirk a spring-assisted knife?

No. The Quirk is a manual knife. The blade can be opened using a flipper or a thumb stud, and the movement is not assisted by a spring-assisted mechanism.

How do you care for G10 grips?

G10 grips can be cleaned with a soft brush and water mixed with a small amount of mild detergent. After cleaning, be sure to thoroughly dry the handle and the steel components of the mechanism.
