Product Description

The Microtech Hera II Mini 1702M-10RX51S is a compact dual-action OTF automatic built for collectors and serious EDC users who want Microtech's M390MK precision in a 1.90 oz package that closes to 3.95 inches. ⚠️ OTF automatic — verify legal status in your jurisdiction before purchasing. Visit akti.org for knife law information.

The blade is ground from Böhler M390MK — Microtech's in-house processed variant of Böhler M390, hardened to 61-62 HRC. M390MK delivers edge retention that far outlasts most production OTF steels while maintaining corrosion resistance for daily carry. The bayonet profile presents a primary cutting edge with a false edge ground partway down the spine from the tip — a single-edged blade that creates the visual character of a double-edged point without the legal restrictions of a fully sharpened second edge. The black stonewash flat grind at 0.09" thin provides a non-reflective working surface with the silver bevel line visible at the edge geometry.

The orange X-51 aluminum handle is Microtech's lightweight slab construction at 0.35" thin — striking visual presence in a platform that carries at 1.90 oz. The double-action thumb slide deploys and retracts the blade via the same slider in opposite directions. Tip-down right carry. Made in the USA.

Microtech Hera II Mini 1702M-10RX51S: Frequently Asked Questions

Common questions about the Microtech Hera II Mini OTF in Böhler M390MK, answered by the Knifeworks team. ⚠️ OTF automatic knife — verify legal status in your jurisdiction before purchasing. Visit akti.org for knife law information.

Is the Microtech Hera II Mini 1702M-10RX51S legal to buy and carry?

The Hera II Mini is a dual-action OTF automatic knife — automatic knives are regulated by state and local law and legality varies significantly by jurisdiction. It is the buyer’s responsibility to verify that OTF automatic knives are legal to purchase, own, and carry in their specific location before ordering. Knifeworks sells this knife only where permitted by law. For current state-by-state legal information on automatic knives, visit akti.org — the American Knife & Tool Institute’s resource for knife law information.

What is Böhler M390MK, and why does Microtech use it in the Hera II Mini?

Böhler M390 is an Austrian particle metallurgy stainless steel known for exceptional edge retention, corrosion resistance, and wear resistance. M390MK is Microtech’s proprietary designation for their specific heat treatment of M390 — the MK suffix means Microtech processes the steel to their own hardness target of 61-62 HRC rather than using standard M390 parameters. For an OTF that opens and closes repeatedly in daily carry, M390MK delivers edge retention that far outlasts most production OTF steels while maintaining the corrosion resistance needed for all-weather carry.

What is the bayonet blade profile on the Hera II Mini?

The bayonet profile on the Hera II Mini features a primary cutting edge with a false edge ground partway down the spine from the tip. The false edge creates a sharpened bevel at the spine near the point — giving the blade the visual character and tip geometry of a double-edged blade — but the false edge does not run the full length of the spine, so the blade is a single-edged design. This is legally distinct from a fully double-edged dagger or Spartan Dagger configuration. The bayonet geometry creates a refined, penetrating tip while the primary edge handles everyday cutting tasks along its full length.

How does the double-action thumb slide work on the Hera II Mini?

The double-action thumb slide is Microtech’s OTF deployment mechanism on the Hera II Mini. Pushing the slider forward fires the blade out of the front of the handle; pulling the slider back retracts and locks it. Both deployment and retraction happen through the same slider in opposite directions — this is what “double-action” means. The mechanism is spring-driven for fast, reliable operation in both directions. The thumb slide is sized for the Hera II Mini’s compact platform — the 3.95” closed length means the slide is ergonomically positioned for secure thumb actuation on the compact handle.

What is X-51 aluminum, and what makes the orange handle distinctive?

X-51 is Microtech’s designation for their aluminum handle construction on the Hera II Mini — a slab-style aluminum design machined to 0.35” thin for a flat, lightweight carry profile. Aluminum provides excellent strength-to-weight ratio; at 1.90 oz total weight, the Hera II Mini is among the lightest OTF platforms Microtech produces. The orange color is anodized into the aluminum surface — an oxide layer that refracts light at orange wavelengths, inherent to the aluminum rather than a paint or coating. The orange X-51 is a high-visibility configuration that gives the Hera II Mini a distinctive visual identity within the Microtech lineup.
