Blade Design

The knife’s blade, made of high-quality CPM S35VN “super” stainless steel, is coated in a non-reflective blackout finish, offering both aesthetic appeal and tactical advantage. Its spearpoint double edge ensures versatility, allowing for both slashing and piercing.


Ergonomically and symmetrically designed with a textured grip from solid G10, the handle ensures that the user maintains control in all conditions, whether it’s a tense self-defense scenario or a simple everyday task. The handles can also be removed with ease to expose the skeleton handles designed for such “naked” grip for further concealment capabilities.


The Pentagon FX comes with a secure sheath integrated with SOG’s Universal Mounting System, allowing it to be carried discreetly and accessed rapidly on a belt, IWB, velcro and MOLLE. This design is rooted in the kind of tradecraft that would make it a suitable companion for any operative.


The balance of weight and size ensures that the knife is comfortable to carry as an everyday tool (EDC) without compromising its effectiveness in a self-defense situation deployed from concealed carry positions.

Self-Defense and as an EDC Option

Self-Defense: Its sharp edge, reinforced by a well-designed handle, allows for quick, precise action. Whether you are a trained professional or an individual concerned about personal safety, the knife’s capabilities are tailored for self-defense scenarios.

Everyday Carry (EDC): The knife’s size and weight make it a practical choice for daily use. From cutting cords to opening packages, its diverse functions make it an essential part of any urban survival kit. However, the double-edged blade may not be ideal for certain cutting tasks or legal carry parameters.

Covert Operative Appeal: With its discreet design, this knife echoes the principles that are integral to the work of a covert operative. The blackout finish, along with its multi-functionality, aligns it with a tradecraft that prioritizes stealth and efficiency.
