Microtech Scarab II Gen III D/E-S OTF Knife OD Green Aluminum, Apocalyptic M390MK by Tony Marfione (1180-10APOD)

Microtech Scarab II Gen III D/E-S OD Green Aluminum, Apocalyptic M390MK by Tony Marfione (1180-10APOD) – full-size tactical-class OTF automatic knife

The Microtech Scarab II Gen III D/E-S OD Green Aluminum, Apocalyptic M390MK by Tony Marfione (1180-10APOD) is a full-size OTF automatic knife featuring the D/A system, designed as a robust construction for heavy-duty use in demanding conditions. This model expands the Scarab II Gen III line, combining a large blade, stable ergonomics, and mechanics designed for quick one-thumb deployment and retraction. The blade, made of Böhler M390MK steel, features a D/E-S Spear Point profile, a flat grind, and an Apocalyptic finish, creating a configuration optimized for effective piercing, controlled cutting, and high durability. The handle is made of 6061 -T6 aluminum / 3M Traction Tape Inlay in the OD Green / Black configuration, an automatic OTF mechanism with a dual spring system, a Thumb Slide, a right/left clip, tip-down orientation, and a glass breaker reinforce the practical and tactical character of the Scarab II Gen III model.

Böhler M390MK – Microtech powder steel for demanding use

Böhler M390MK is a high-performance powder steel developed for Microtech in collaboration with Böhler, designed with a focus on wear and corrosion resistance as well as long-lasting sharpness. In the Scarab II Gen III model, this material performs well when cutting straps, cords, tapes, cardboard, plastics, and technical materials, where edge stability and predictable blade performance are essential. The Apocalyptic finish gives the blade a rugged, slightly weathered look and helps mask minor marks that develop during regular use.

D/E-S Spear Point and flat grind – symmetry, penetration, and control

The D/E-S Spear Point profile features a double-edged blade with symmetrical geometry, designed for precise tip control and effective piercing. Grain grooves on both sides of the blade visually reinforce the construction and emphasize the technical character of the Scarab II model. The flat grind facilitates smooth cutting through materials while maintaining an optimal balance between cutting edge sharpness and durability. This combination allows the D/E-S variant to effectively blend the task-oriented nature of a large OTF knife with the high-quality craftsmanship typical of Microtech.

Dual OTF and Thumb Slide Mechanism – Power, Speed, and Reliability

The Scarab II Gen III utilizes the D/A OTF automatic mechanism, which allows the blade to be extended and retracted using the same Thumb Slide. This generation features a dual spring system, increasing the mechanism’s operating force and smoothness compared to older designs. The knurled slide with a distinctive “X” pattern in the center requires deliberate pressure, which enhances safety and reduces the risk of accidental activation. The design allows for comfortable use with both the right and left hand.

OD Green Aluminum and 3M Traction Tape Inlay – a stable grip for a large OTF

The handle, made of 6061-T6 Aluminum / 3M Traction Tape Inlay, was designed with a focus on rigidity, durability, and a secure grip. The aluminum body in OD Green gives the knife a tactical, field-ready look, while the 3M Traction Tape Inlay enhances grip during heavy-duty use, even when wearing gloves or in less stable conditions. Jimping on the spine and spine base improves grip control, and the massive right/left deep-carry, tip-down clip allows for discreet carrying of the knife. A window breaker with a tungsten carbide ball expands the design’s functionality in emergency situations.

Technical Data

Frequently Asked Questions

How to care for and sharpen the Böhler M390MK steel in the Scarab II Gen III model?

Böhler M390MK steel should be cleaned and dried after use, especially after contact with moisture, sweat, or debris from cut materials. A diamond sharpener or a high-quality ceramic system works best for sharpening, as powder steel with high wear resistance requires an effective abrasive and a stable angle.

How does the D/A OTF mechanism work in the Microtech Scarab II?

The D/A OTF mechanism allows the blade to be extended and retracted by sliding the same Thumb Slide. The blade moves back and forth along the handle’s axis, so the knife can be operated with one hand without the need for a classic side-to-side opening action.

What makes the D/E-S Spear Point profile stand out?

D/E-S Spear Point refers to a double-edged blade with symmetrical geometry, designed for precise tip control and effective piercing. This profile is well-suited for a full-size, task-oriented OTF knife.

What does the 3M Traction Tape Inlay offer?

3M Traction Tape Inlay is an inlay with a non-slip texture that improves grip stability. It facilitates control of a large OTF knife during heavy-duty work, even when wearing gloves or in less stable conditions.

Does the Microtech Scarab II Gen III have a glass breaker?

Yes, the handle features a glass breaker with a tungsten carbide ball. This 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.
