108,53 €ASP Police Duty Black G10, Stonewashed AUS-8 – Assisted-Opening Folding Knife
The ASP Police Duty Black G10, Stonewashed AUS-8 folding knife (55722) is a folding knife with a spring-assisted opening mechanism, featuring a Drop Point blade made of AUS-8 steel, a black G10 handle, and a Liner Lock. The stonewashed finish gives the blade a rugged, utilitarian look and helps minimize the appearance of minor scratches and scuffs.
The flipper or hole in the blade activates the Assisted Opening mechanism, which aids in further opening the blade. The Quick-Release system, which uses a handcuff key, allows you to move the steel clip to the right or left side of the handle without the traditional unscrewing of the mount, enabling tip-down carry.
AUS-8 – Steel for Everyday Use
The blade is made of AUS-8 stainless steel. This material offers good corrosion resistance, easy edge maintenance, and properties suitable for a regularly used work folder.
Drop Point, Plain Edge, and Stonewashed
The Drop Point profile features a gently sloping spine, a sturdy tip, and a rounded belly. The Plain Edge is ideal for precision cutting, while the Stonewashed finish helps mask some of the signs of daily wear.
Black G10 and Grooved Grip
The black G10 grips feature a milled Grooved Grip texture that enhances grip and control. Additional Shark Fin jimping improves thumb support, and the Thin Blue Line detail highlights the character of the Police Duty series.

Frequently Asked Questions
How do I care for AUS-8 steel?
After use, clean the blade and dry it thoroughly. Before long-term storage, apply a thin layer of preservative, especially after contact with moisture, salt, or organic substances.
How do I sharpen a Drop Point blade?
Guide the edge at a constant angle, gradually rotating the knife along the rounded spine. Near the tip, it’s best to reduce pressure to preserve its factory profile.
How does the assisted opening mechanism work?
Pressing the flipper initiates the blade’s movement, and the Assisted Opening mechanism helps it open further. Once fully extended, the blade is secured by the Liner Lock.
How does the Quick-Release clip work?
The system allows you to move the clip to the right or left side of the Handle without the standard removal of screws, using a handcuff key (not included). Before carrying the knife, check that the clip is properly seated and locked.
How do I clean a G10 handle?
The handle can be cleaned with a soft brush and mild detergent. Pay special attention to the Grooved Grip grooves, where dust and small particles can accumulate.
