Microtech Hera II Mini T/E Signature Outbreak Aluminum OTF Folding Knife, Outbreak M390MK by Tony Marfione (1704M-1OBDS)

The Microtech Hera II Mini 1704M-1OBDS is a compact OTF automatic knife from the Signature Series, featuring a distinctive Outbreak decorative finish and deep engraving. The model features a blade made of M390MK steel, an aluminum handle, and a Double-Action OTF mechanism with the Dual-Fuel Drive Train™ system.

The 73.66 mm blade has a Tanto profile, a flat grind, and an Outbreak finish. The Outbreak motif also extends to the aluminum body, creating a stylistically cohesive Signature Series model.

M390MK – Steel for a Compact Automatic Knife

The blade is made of M390MK steel, a variant of M390 developed for Microtech in collaboration with Böhler. The material offers high resistance to abrasion and corrosion.

Tanto, flat grind, and Outbreak

The Tanto profile is distinguished by a strong tip and clearly defined edge geometry. The flat grind supports efficient cutting, while the Outbreak finish, combined with deep engraving, gives this version its distinctive look.

Outbreak Aluminum and Dual-Fuel Drive Train™

The handle is made of aluminum and finished with the Outbreak, Deep Engraved motif. Its design also incorporates a rear section that serves as a backspacer.

The Double-Action OTF mechanism allows the blade to be extended and retracted using a single slider. The Dual-Fuel Drive Train™ system powers the mechanism, and the 6AL4V titanium clip allows for right- or left-side carry in a tip-down configuration.
