The Active Response Kerambit (ARK) was co-designed by Dirk Pinkerton and Chad McBroom.  The ARK is a specialized blade intended for support-hand use in firearm-retention scenarios, though not limited to such application.

The ARK’s middle-finger ring coupled with its ergonomic finger grooves and an index-finger tension bar allows the user to retain the ARK while manipulating their firearm.  The ARK is designed to lock into the user’s hand, offering full dexterity of the support-hand for firearm manipulation.  The user is able to reload, clear stoppages, establish an effective two-handed shooting grip (thanks to the specially curved spine), and even grab or redirect an opponent, without having to ditch their edged weapon or lose precious time by sheathing the blade.

The ARK is one of the most versatile, functional, and well-thought-out tactical knife designs on the market.  It is the first and only knife designed specifically for the professional gun-toter with the capability of being used in conjunction with the firearm without compromising support-hand function.

The ARK is made by Pinkerton Knives and comes with a molded kydex sheath (1″ hole spacing) that is compatible with the Spyderco G-Clip attachment (not included) for vertical and horizontal belt mounting, or can be lashed to gear or worn as a neck knife with the supplied 550 cord.

The Gen II ARK is a slightly modified version of the original ARK.  It has a hole just behind the cutting edge which serves as a locking mechanism with the sheath.  This allows the sheath to be cut lower, allowing the user to establish a full grip before drawing the blade.
