Couteau pliant Audacious Concept Aculis - M390 - Titanium, DLC

The Aculis is the latest creation from Audacious Concept - a precision-engineered folding knife that reflects the brand’s philosophy of minimalist design and uncompromising performance. The name Aculis comes from Latin, meaning “sharp vision”, symbolizing both the knife’s clean geometry and its focus on detail and precision.

Design and Construction

The Aculis features a Spear Point blade made from premium M390 stainless steel, known for exceptional edge retention, corrosion resistance, and toughness. Its triple finish - Satin + Blastwash + DLC - creates a deep black surface that emphasizes the lines of the blade while improving wear and scratch resistance. Flat grinds provide a perfect balance between slicing performance and tip strength.

The handle is machined from solid titanium with a DLC-coated Deep Grey Smooth Stonewash finish, offering a sleek matte look and outstanding durability. Internal milling reduces weight without compromising strength, resulting in a balanced knife weighing just 105 g (3.7 oz).

Mechanism and Ergonomics

The Frame Lock mechanism features a steel lockbar insert with overtravel protection, ensuring long-term reliability and precise lockup. The blade operates on a double-row ceramic bearing system in a brass cage, providing glass-smooth deployment via dual thumb studs - crisp, fast, and secure.

The pivot screw houses a watch-grade luminous insert, glowing softly in low light. The knife’s construction is based on two main connection points - the pivot and rear spacer - resulting in a clean, well-balanced, and easily serviceable design.

Details that Matter

A milled titanium pocket clip provides secure pocket carry and includes an engraved serial number, highlighting each knife’s individuality. A lanyard hole is positioned on the rear frame for added versatility. The two-tone laser engraving on the handle and clip reveals its intricate pattern when viewed under light - a refined detail that embodies precision and craftsmanship.
