    MANUFACTURING PROCESS:

    The Herman Knives Sting is what happens when a dress-carry silhouette gets built like a serious cutting tool. It’s slim, pocket-friendly, and clean enough for office carry, but the materials and mechanics are pure high-end folder: Böhler M390 blade steel, Grade 5 titanium everywhere that matters, and Herman’s updated bearing setup tuned for fast, stable action.

    The blade is M390 powder stainless, heat treated with deep cryo (liquid nitrogen) to 61 HRC. The flat grind gives you a practical balance—efficient slicing, strong support behind the edge, and a profile that doesn’t feel delicate. A stonewash finish keeps it low-maintenance and wearable, especially if this is a knife you actually carry instead of just admire.

    Then there’s the handle: the Puzzle pattern titanium scale with those shifting blues, purples, bronzes, and charcoal tones. It’s a bold finish, but still refined—more “custom watch dial” than “loud art piece.” Add the titanium backspacer, titanium clip, and titanium lock side, and you get the full Herman feel: light in hand, rigid in use, and crisp in the pocket.

    The action is where the Sting quietly flexes. Herman uses custom ceramic caged bearings, and the latest update adds increased stability with 16 ceramic balls. On top of that, the knife runs on M390 steel washers finished with careful machining, EDM work, and fine lapping—done in-house. The goal is simple: smoother deployment, less wear, and consistency over time. A ceramic detent ball, tungsten-carbide lock insert, and tungsten-carbide stop pin round out the long-term durability package.

    Included: original Herman box with microfiber cloth, Pruciak Protector Glide for Herman oil, and a dedicated in-house titanium screwdriver.

    PACKAGE CONTENTS: Certificate of authenticity, white cotton gloves, protective packaging.
