The ARN is a slipjoint folder featuring the same double-detent system used in my Monte Carlo and Casino custom models. This mechanism securely holds the blade open and closed without a traditional lock, providing a safe and compliant everyday carry option in most regions.

A defining feature is its ultra-low-profile flipper. Previously referred to as a front flipper, I now simply call it a flipper — discreet, intuitive, and designed to maintain a clean silhouette.

The handle integrates a precision-machined T-slot inlay system. A single screw secures the ambidextrous titanium clip. When the clip is removed, both inlays can slide out effortlessly without tools. A small titanium insert replaces the clip, locking the inlays in place and preserving the handle’s symmetry.

A central element of the ARN is the inlay system. We will offer a wide range of inlay materials, enabling true personalization. Currently, six different fiber materials are available.

The ARN is also the first Shop Built folder available with an upgraded Damasteel blade. The chosen pattern is ROSE, deeply etched and brushed to achieve a distinct yet understated expression. Refined and subtle — just like the ARN itself.
