Microtech Hera II Mini OTF AUTO Knife 3" M390MK Black Double Edge Bayonet Blade, Red Deep Engraved Aluminum Handle

The Microtech Hera II Mini OTF AUTO delivers high-performance precision in a compact, collectible package. Inspired by the legendary Troodon series, this dual-action out-the-front automatic combines Microtech’s iconic engineering with a sleeker, lighter form tailored for both daily carry and professional use.

At the heart of this knife lies a 3-inch Böhler M390MK double-edge bayonet blade, known for exceptional sharpness retention and corrosion resistance. Its black finish contrasts beautifully with the deep-engraved red aircraft aluminum handle, showcasing Microtech’s unmistakable design language and flawless machining.

The handle features precision-milled jimping for a secure grip and a minimal hardware layout, with only a single discreet screw near the butt for clean symmetry. The reversible titanium pocket clip allows both right- and left-handed tip-down carry, while Microtech’s signature step-textured thumb slide ensures positive deployment and retraction.

Designed by Tony and Sean Marfione, the Hera II Mini blends form and function with artful execution — a standout in the world of high-end automatic knives. Whether displayed, carried, or put to work, it embodies the essence of American-made precision.
