KB KNIVES Yondu KB420C Double Detent Folder – DLC Micro Milled Titanium Reversible Tanto M390 Tactical EDC Knife Guide
For tactical fans and lightweight EDC collectors seeking a slim, unique double detent folder, the KB Yondu KB420C stands out with one-of-a-kind mechanism and premium all-titanium construction. Designed by renowned knife maker Ostap Hel and manufactured in China, this pocket knife is covered by a lifetime warranty, built to serve daily utility tasks and light tactical applications, with ambidextrous geometry fitting both left and right-handed carriers perfectly.
Its standout cutting tool is a 2.87-inch Bohler M390 tanto blade, the gold standard of high-performance stainless steel famous for exceptional edge retention and corrosion resistance. Every blade undergoes strict vacuum and cryogenic heat treatment to achieve HRC60-62 hardness, paired with a flat plain edge sharpened at a factory angle of 15° to 20°. The clean satin finish delivers low-reflection cutting performance, ideal for slicing, piercing and heavy-duty daily chores. Fully extended, the knife hits 7.05 inches total length while weighing merely 2.97 oz (84 g), drastically cutting down pocket burden for all-day carry.
The handle adopts solid titanium with precise horizontal micro milling, fully coated in scratch-resistant DLC black to create a sleek stealth tactical look. The fine milling lines add subtle non-slip grip without bulk, and the ultra-slim 0.43-inch thickness lets the Yondu slip seamlessly into any pocket or tactical pouch. Unlike traditional liner or frame locks, this model uses a reliable double detent lock system, paired with caged ceramic ball bearings for ultra-smooth, consistent blade flicking every time.
All external hardware matches the unified DLC titanium finish, including backspacer, pivot cap and mounting screws. A major practical upgrade is its reversible titanium pocket clip, supporting tip-up carry on both left and right sides so users can fully customize their carry style. Beneath the titanium scales sit black PVD finished stainless steel liners, boosting structural stability without adding extra weight.
Combining rare double detent action, top-tier M390 tanto steel, reversible carry design and featherlight titanium build, the KB Yondu KB420C delivers unmatched value for anyone after a compact, reliable tactical EDC folder that balances unique mechanics and everyday functionality.
