MSI S/E Ram-Lok Tactical Black Tri-Grip Polymer, Black DLC folding knife, combining strength, durability, and elegance. Its blade is made of premium M390MK steel, the result of a collaboration between two renowned companies—Microtech and Böhler. This steel is known for its exceptional durability and long-lasting sharpness, making this knife ready for any challenge. The intuitive RAM-Lok lock ensures safety during use. This innovative lock is easy to operate and provides ease of use for both right- and left-handed users. The knife’s handle is made of polymer, durable and ergonomic. Its shape is designed to fit perfectly in the hand, ensuring comfort even during prolonged use. This knife is not just a tool, but also a work of applied art. Its designer, Anthony Marfione, founder and owner of Microtech, paid attention to every detail. From the elegant black finish to the satin details, this knife is both beautiful and practical. Whether you’re looking for a reliable tool or an elegant accessory, the MSI (Microtech Standard Issue) folder will meet your expectations.

M390MK - thanks to the collaboration between engineers from Microtech and Böhler, an exclusive version of M390 steel was created exclusively for Microtech. The carbon content was increased and subjected to more rigorous control, thereby improving the properties of M390 steel to ensure better edge retention, corrosion resistance, and polishability. A martensitic high-performance chromium steel produced using powder metallurgy. Due to its alloy composition, it features exceptionally high wear resistance and high corrosion resistance. Thanks to its high wear resistance, it maintains edge shape effectively, allowing the blade to retain its sharpness for a very long time (requires minimal maintenance). Another advantage is its resistance to “wire” formation during sharpening. Steel with a high chromium content of 19.0% (Cr), alloyed with 1.95% carbon (C) and 4.0% vanadium (V), hardened to a range of 59–61 HRC. This super steel is comparable to Carpenter’s CPM 20CV or CTS-204P steels. Manufactured by Böhler Edelstahl in Kapfenberg, Austria.

Ram-Lok (Crossbar Lock) – a crossbar that moves horizontally within longitudinal slots in the steel side plates of the handle frame. When the knife is opened, the locking bar engages from above onto the rear part of the blade, preventing it from moving back. This bar is pressed down by two springs. Unlocking occurs by pulling the locking bar backward; its ends are accessible through notches in the side plates of the handle. In the closed position, the bar presses against the cam surface at the rear of the blade, preventing it from opening spontaneously. The advantages of the Ram-Lok lock include resistance to contamination, practical insensitivity to dynamic loads, ease of operation with both the right and left hand, and smooth operation.

DLC (Diamond Like Carbon) enhances the blade’s surface durability with a black, matte nanocomposite coating that exhibits unique properties such as exceptional hardness and low friction, as well as excellent corrosion resistance. It is one of the most scratch- and wear-resistant coatings used in industry, including the knife industry.

Blade - machine-ground Sheepfoot style, single-edged S/E (Single Edge). Finished with a DLC coating that masks minor scratches caused during use. Opens via a thumb hole in the blade, making it easy to use for both right- and left-handed users. The blade features a high flat grind, providing excellent cutting edge geometry and extreme cutting performance. To maintain full control over the blade, the blade spine features upper jimping, a serrated thumb rest. The entire knife is secured with a convenient Ram-Lok lock.

Handle - made of durable polymer in the same color as the blade coating, covered with Tri-Grip texture for a better grip. Wide lock slider with Microtech’s signature stepped X pattern. Both scales are secured with a solid aluminum backspacer. A reversible (right/left) clip allows for discreet tip-up carry. Above the clip is a lanyard hole for a safety or decorative cord.
