The Kershaw Secret Agent 4007 is a tactical boot knife featuring a black-oxide 8Cr13MoV blade, rubberized grip, and a dual-carry sheath for discreet concealment.

Kershaw Secret Agent Overview

The Kershaw Secret Agent (4007) is a modern update to the classic boot knife, designed for discreet carry and reliable tactical performance. Specifically, this fixed blade features a 4.4-inch spear point blade crafted from 8Cr13MoV stainless steel, a heat-treated alloy known for its strength and edge retention. Moreover, the blade is finished with a non-reflective black-oxide coating, which provides essential corrosion resistance and ensures the knife remains stealthy in low-light conditions. Furthermore, while the profile suggests a double-edge dagger, this knife features a single sharpened edge, making it legal to carry in more jurisdictions while still offering a strong piercing tip.

Grip and Handling

The handle of the Secret Agent is engineered for a secure, non-slip grip in high-stress situations. It features a rigid glass-filled nylon core with a textured rubber overmold, delivering the perfect balance of durability and “stickiness.” This co-molded design ensures the knife stays firmly in your hand, even in wet or muddy environments. Additionally, the handle includes a generous lanyard hole, allowing you to add a paracord tether for extra security or faster deployment. If you are looking for an even smaller, lighter fixed blade for deep concealment, we recommend the Kershaw Brace Fixed Blade Neck Knife.

Dual-Carry Sheath System

In addition to the knife, the Secret Agent comes with a versatile molded sheath designed for multiple carry options. The sheath features a sturdy steel clip optimized for boot carry, allowing you to secure the knife inside your footwear for ultimate concealment. Alternatively, the sheath body includes slots for leg straps, giving you the option to mount it to your thigh or attach it to a gear vest. Furthermore, the sheath provides retention without snaps or straps, allowing for a silent and rapid draw when seconds count.
