Microtech Socom Delta Ram-Lok – a tactical folding knife in OD Green

Microtech Socom Delta Ram-Lok S/P-M OD Green Aluminum, Stonewashed M390MK (159RL-10OD) is a premium manual folding knife that expands the Socom line with a modern Ram-Lok lock, ambidextrous operation, and a sturdy aluminum construction. The model combines the tactical design principles of the Socom series with more modern mechanics, including smooth opening via dual thumb studs and a reversible tip-up clip. The handle, made of 6061-T6 aluminum in OD Green, gives the knife a rugged, utility-oriented character while maintaining high rigidity and a secure grip.

The blade, made of Böhler M390MK steel, features an S/P-M / Spear Point profile, a hollow grind, and a Stonewashed finish—a combination designed for precise tip control, aggressive edge penetration, and high durability. Ball bearings ensure smooth blade operation, and the integrated glass breaker expands the design’s functionality in emergency situations. This is a large tactical folding knife for users who expect stability, a strong lock, and high-quality craftsmanship.

Böhler M390MK – Microtech’s powder-metals steel for demanding tasks

Böhler M390MK is a high-performance powder-metals steel used by Microtech, developed with a focus on wear resistance, corrosion resistance, and long-lasting cutting edge retention. In the Socom Delta Ram-Lok model, this material performs well when cutting cardboard, straps, cords, plastics, and technical materials, where blade stability and predictable edge performance are essential.

The Stonewashed finish gives the blade a rugged, slightly matte appearance and helps mask minor signs of regular use. Paired with the OD Green handle, it creates a more field-ready and practical interpretation of the Socom series, without compromising the precision craftsmanship characteristic of Microtech knives.

S/P-M Spear Point and hollow grind – precision at the tip and aggressive cutting

The S/P-M / Spear Point profile provides a clearly defined tip that facilitates precision work with the blade, scoring, and controlled blade guidance. This geometry is well-suited for a tactical folder, as it combines tip stability with an effective cutting edge. Long grain patterns on both sides of the blade reinforce the model’s technical appearance and emphasize its functional character.

The hollow grind increases the aggressiveness with which the edge penetrates the material, improving cutting performance on straps, cardboard, plastic film, cords, and fibrous materials. In practice, this means a very smooth start to the cut and good control over the blade during tasks requiring precision. The combination of M390MK steel, a hollow grind, and a stonewashed finish creates a blade ready for regular use in demanding environments.

OD Green Aluminum and Ram-Lok – a secure grip and two-handed operation

The handle, made of 6061-T6 aluminum, was designed with an emphasis on durability, rigidity, and control during heavy-duty use. The OD Green color highlights the knife’s outdoor character, while the multi-faceted geometry, pronounced finger grooves, and milled spine support a stable hand position. The design remains comfortable even when wearing gloves and during dynamic grip changes.

The Ram-Lok lock acts as a crossbar mechanism accessible from both sides of the Handle, making the knife comfortable for both right- and left-handed users. Opening via the dual thumb stud is quick and intuitive, and ball bearings ensure smooth blade movement. The reversible right/left tip-up clip allows you to customize how you carry the knife to suit your preferences.

Technical data

Frequently Asked Questions

How do I care for and sharpen the Böhler M390MK steel in the Socom Delta Ram-Lok model?

Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or dirt. A diamond sharpener or CBN system works best for sharpening, as this high-wear-resistant powder-metal steel requires an effective abrasive.

How does the Ram-Lok lock work?

Ram-Lok uses a transverse bar that moves within the handle’s guides. When opened, the bar locks the rear part of the blade, and access from both sides facilitates use with either the right or left hand.

What makes the S/P-M Spear Point profile stand out?

S/P-M / Spear Point provides a precisely guided tip and balanced blade geometry. This profile works well for scoring, precision work, and controlled cutting of technical materials.

How does the Socom Delta Ram-Lok differ from the classic Socom Elite Manual?

The Socom Delta Ram-Lok uses a Ram-Lok locking mechanism operated from both sides of the Handle, while classic Socom Elite Manual models typically use a Liner Lock. The Ram-Lok version also features a right/left-hand tip-up clip.

Does the Microtech Socom Delta Ram-Lok have a glass breaker?

Yes, the model has an integrated glass breaker. It is a structural element of the knife that expands its functionality in emergency situations, but it is not listed as a separate accessory in the technical data.
