The model features a spring-assisted opening mechanism, an AUS-8 steel Drop Point blade, a Liner Lock, and a decorative “Battle Rattle” motif engraved on the blade.
The black PVD coating serves as a backdrop for the engraving, while the G10 handle ensures a secure grip. The flipper or hole initiates the blade’s opening, and the Quick-Release clip allows you to change the carrying side without having to remove the screws.
AUS-8 and Black PVD
AUS-8 stainless steel offers good corrosion resistance and easy edge maintenance. The Black PVD coating gives the blade a dark appearance and highlights the decorative nature of the engraving.
“Battle Rattle” engraving on the blade
The “Battle Rattle” motif is engraved directly onto the blade, setting this version apart from standard Police Duty models. The decorative finish gives the knife a collector’s item feel while retaining the functional design of the base PDK model.
Assisted Opening and Black G10
The flipper or opening hole activates the assisted opening mechanism, and the Liner Lock secures the blade in the open position. The black G10 handle features a textured surface that enhances grip control.

Frequently Asked Questions
How do I care for AUS-8 steel?
The blade should be cleaned regularly and dried thoroughly. After contact with moisture or organic substances, it is recommended to apply a thin layer of preservative.
How do I sharpen a Drop Point blade?
The edge should be sharpened at a consistent angle, following the curve of the blade belly. Near the tip, reduce pressure to preserve the factory geometry.
How do you care for an engraved blade?
Clean the blade with a soft cloth, without using harsh abrasives. Avoid vigorous polishing, which could alter the appearance of the engraving and the PVD coating.
How does Assisted Opening work?
Pressing the flipper initiates the opening, and the assist mechanism continues the blade’s movement. Once fully open, the blade is secured by the Liner Lock.
How does the Quick-Release clip work?
The clip can be moved to the right or left side of the Handle using a handcuff key (not included). After repositioning, make sure the locking mechanism is properly secured.
