Microtech Scarab II Gen III T/E Signature OTF Knife Outbreak Aluminum, Outbreak M390MK by Tony Marfione (1279-1OBS)

Microtech Scarab II Gen III T/E Signature Outbreak Aluminum, Outbreak M390MK by Tony Marfione (1279-1OBS) – Signature-class tactical OTF automatic knife

The Microtech Scarab II Gen III T/E Signature Outbreak Aluminum, Outbreak M390MK by Tony Marfione (1279-1OBS) is a full-size OTF automatic knife featuring the D/A system, designed as one of the strongest and most advanced designs in Microtech’s lineup. This model builds on the Scarab II concept, retaining its massive geometry, high durability, and reliable performance in demanding conditions. The blade, made of Böhler M390MK steel, with a T/E (Tanto Edge) profile, a flat grind, and an Outbreak finish, creates a configuration optimized for a strong tip, effective piercing, and long-lasting edge performance. The handle, made of 6061 -T6 aluminum / 3M Traction Tape Inlay with an Outbreak finish ensures a very secure grip, while the automatic OTF mechanism with a dual spring system, Thumb Slide, right/left clip, tip-down orientation, and glass breaker reinforce the utility and tactical character of this Signature version.

Böhler M390MK – Microtech powder steel for heavy-duty use

Böhler M390MK is a high-performance powder steel developed for Microtech in collaboration with Böhler, designed with a focus on wear resistance, corrosion resistance, and 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 Outbreak version gives the blade a distinctive, collectible character while still fitting into a working aesthetic that effectively masks signs of regular use.

T/E (Tanto Edge) and flat grind – reinforced tip and effective cutting

The T/E (Tanto Edge) profile provides a distinctly reinforced tip, useful for precision work, scoring, and tasks requiring greater tip strength. The flat grind facilitates smooth gliding of the blade through material, maintaining a favorable balance between cutting efficiency and structural strength. Grain grooves on both sides of the blade enhance the blade’s technical appearance and emphasize the Scarab II’s character as a large, task-oriented OTF automatic knife.

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

The Scarab II Gen III utilizes a D/A OTF automatic mechanism, which allows the blade to be extended and retracted using the same Thumb Slide slider. This generation features a dual spring system, increasing the mechanism’s power and reliability while improving smoothness of operation compared to older designs. The knurled slider with a distinctive “X” pattern in the center requires deliberate pressure, which enhances safety and reduces the risk of accidental activation. The system can be comfortably operated with either the right or left hand.

Outbreak Aluminum and 3M Traction Tape Inlay – a grip for demanding conditions

The handle, made of 6061-T6 Aluminum / 3M Traction Tape Inlay, is designed for maximum grip control. The aluminum body provides high rigidity, and the 3M Traction Tape Inlay with its aggressive texture significantly increases hand grip, even when working with gloves or in more challenging conditions. The Outbreak finish gives the handle the distinctive look of the Signature version, and the jimping on the spine and underside support grip stability. The right/left deep carry clip, tip-down, allows for discreet carrying, and the glass breaker with a tungsten carbide ball expands the knife’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-fold mechanism.

What makes the T/E (Tanto Edge) profile stand out?

T/E (Tanto Edge) provides a strong, clearly defined tip and a geometry well-suited for technical tasks. This profile works well for scoring, precision work, and cutting materials that require greater control of the blade tip.

What does the 3M Traction Tape Inlay offer?

3M Traction Tape Inlay is an inlay with an aggressive, 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.
