Microtech MSI: A Tactical Standard for the Modern Knife User

At CajunKnife.com, we understand that a quality folding knife is more than a tool—it’s a commitment to precision, reliability, and performance. The Microtech MSI (Microtech Standard Issue) embodies that philosophy, bringing a new level of engineering to the manual folder category. Built in the USA and backed by Microtech’s reputation for innovation, the MSI is a purpose-driven knife that sets the bar for everyday carry in tactical environments.

Designed for Demanding Hands

The MSI isn’t just another addition to the EDC market—it’s Microtech’s answer to the growing demand for a dependable, manual folding knife that can hold up in hard-use scenarios. Everything about this blade is deliberate, from its robust build to its cutting-edge materials.

Blade Profile

At the heart of the MSI is a 3.88-inch blade crafted from Microtech’s proprietary M390MK steel. This premium material offers exceptional edge retention, wear resistance, and corrosion protection—making it ideal for professionals who depend on consistent performance.

The blade is available in both plain and partially serrated options, with finishes ranging from satin to stonewashed and black-coated variants. Its aggressive drop point profile excels at slicing, piercing, and utility tasks, with a thickness that gives the blade backbone without compromising cutting efficiency.

RAM-LOK™: Precision Locking Meets Ambidextrous Control

Microtech’s patented RAM-LOK™ mechanism is central to the MSI’s innovation. This robust bar-lock system delivers a secure blade lock-up with smooth, reliable actuation. Dual textured release buttons—shaped in Microtech’s signature “X” motif—provide a tactile, ambidextrous unlocking experience, ensuring fast, safe operation whether you’re left- or right-handed.

This mechanism not only ensures functional safety but gives the MSI a unique operating feel—snappy, solid, and confidence-inspiring with every deployment.

Ergonomics and Material Options

The MSI’s ergonomic design is a study in user-focused engineering. The handle is sculpted for a natural grip, with pronounced finger grooves and jimping that enhance control during extended use. Whether you’re in gloves or bare-handed, the MSI feels secure and ready for action.

Two handle material options are available:

• Carbon Fiber Laminate: Lightweight, stylish, and rigid—ideal for those looking for a premium feel with a sleek look.
• Injection-Molded Polymer: Durable, impact-resistant, and cost-effective—perfect for field use or harsher environments.

Each handle option features steel liners and a machined titanium backspacer for added structural integrity.

Carry and Deployment

At just under 5 ounces, the MSI is well-balanced for daily carry. A deep-carry, reversible pocket clip allows discreet and customizable carry, while the rear lanyard slot gives additional attachment options for tactical users or those in outdoor professions.

Thanks to the ambidextrous design of both the RAM-LOK system and the clip, the MSI is equally well-suited for right- or left-handed users.

Built to Perform. Built in the USA.

Microtech has long been known for their commitment to American craftsmanship, and the MSI is no exception. Every component is precision-machined, assembled, and tested in the United States to meet the rigorous standards that professionals demand.

From law enforcement and military personnel to hard-use enthusiasts and everyday carry aficionados, the MSI delivers uncompromising performance in a compact, versatile platform.
