Microtech Hera II Mini Bayonet Signature OTF Knife Outbreak Aluminum, Outbreak M390MK by Tony and Sean Marfione (1701M-1OBDS)

Microtech Hera II Mini Bayonet Signature Outbreak Aluminum, Outbreak M390MK by Tony and Sean Marfione – Compact OTF Signature Series

Hera II Mini Bayonet Signature Outbreak Aluminum OTF automatic knife, Outbreak M390MK by Tony and Sean Marfione (1701M-1OBDS) is a compact Signature Series model that combines the modern Hera II Mini platform with one of the most distinctive finishes in the Microtech lineup. The Outbreak variant features a green color scheme with contrasting red blood-splatter accents applied to both the blade and the aluminium chassis. A deeply engraved Biohazard symbol completes the design, giving the knife an instantly recognizable, collectible character.

The Bayonet blade is crafted from Böhler M390MK steel, offering excellent edge retention together with high resistance to wear and corrosion. Automatic blade deployment and retraction are handled by a D/A (Double-Action) OTF mechanism featuring the redesigned Dual Fuel Drivetrain, delivering fast, smooth and decisive operation.

The Hera II Mini utilizes internal hardware, allowing the exterior surfaces of the handle to remain exceptionally clean and minimalist. The redesigned thumb slide area has been optimized to reduce friction and improve the movement of fine debris away from the mechanism. The design is completed by a precision-engineered 6AL4V titanium pocket clip, a Silicon Carbide roller element and a glass breaker. Together, these features reinforce the knife’s technical, functional character while further elevating its premium construction.

Böhler M390MK and Flat Grind

The blade is made of Böhler M390MK steel, which ensures high corrosion resistance and good edge retention. The flat grind facilitates controlled cutting while maintaining the slim and precise geometry of the Bayonet profile.

Bayonet and Outbreak Finish

The Bayonet profile is distinguished by its slender, symmetrical line and precise tip. The Plain Edge is ideal for everyday tasks, while the Outbreak finish, which covers both the blade and the Handle, gives the Signature Series variant its distinctive, irregular styling.

Outbreak Aluminum and Dual Fuel Drivetrain

The aluminum chassis features the Outbreak finish while maintaining a minimalist look thanks to internal structural screws. Dual Fuel Drivetrain ensures smooth Double Action OTF operation, while the modified button pocket reduces slider resistance and helps clear debris from its operating area.

Technical Data

Frequently Asked Questions

How do I care for Böhler M390MK steel?

After use, clean the blade and dry it thoroughly. For long-term storage, it is recommended to protect the surface with a thin layer of a knife-specific preservative.

How do I sharpen the Bayonet blade?

The Plain Edge should be sharpened at a constant angle and with moderate pressure. Around the tip, it’s best to handle the tool with particular care to preserve the slender geometry of the Bayonet profile.

How does the Double Action OTF work?

The thumb slide controls both the deployment and retraction of the blade. Sliding it forward causes the blade to open automatically, while sliding it in the opposite direction automatically retracts the blade into the Handle.

How do you clean the Dual Fuel Drivetrain and button pocket?

The slide area and blade opening should be regularly cleaned of dust, lint, and other small debris. The button pocket’s design helps reduce friction and direct debris away from the slide’s main working surface, but the mechanism still requires periodic cleaning.

How to safely store the Hera II Mini Outbreak?

The knife should be stored with the blade fully retracted, in a dry place, and out of reach of unauthorized persons. Before putting it away, it’s a good idea to check that the slide mechanism is working properly and to remove any debris from the blade slot.
