KB KNIVES Navigator KB458A Frame‑Lock Flipper Knife – Contoured Micro‑Milled Sandblasted Titanium Handle,3.39‑Inch Satin Bohler‑M390 Tanto‑Blade for Tactical & EDC Use
Expertly designed by PG Knives, the KB Navigator KB458A delivers aggressive tactical‑inspired styling alongside high‑end cutlery‑grade performance for EDC lovers and tactical‑focused users. Manufactured in China and backed by a lifetime manufacturer’s warranty, this ambidextrous‑friendly flipper knife is well‑suited for heavy‑duty daily cutting, outdoor tasks and light tactical‑style work.
Its robust cutting core is a 3.39‑inch Bohler M390 tanto‑point blade. The angular tanto profile offers powerful piercing performance and dependable slicing capacity ideal for tactical‑orientated tasks. Every blade undergoes strict vacuum plus cryogenic heat‑treatment to achieve stable HRC60‑62 hardness. It is built with a compound‑ground plain edge factory‑sharpened at 15‑20‑degree angles to maintain long‑term sharpness, while its clean satin finish shows natural metal texture and resists daily abrasion. When fully opened, the knife reaches a total length of 8.27 inches and weighs 4.41 oz (125 g). The moderate weight brings solid reassuring feedback without being burdensome during pocket‑carry.
The handle is precision‑machined from solid titanium with sandblasted finishing. It adopts contoured ergonomic shaping matched with directional micro‑milling grooves across scales. The detailed milling patterns enhance grip friction and prevent slippage under heavy‑use conditions, also adding premium visual appeal. At a thickness of 0.51 inches, the frame balances sturdy structure and comfortable hand‑filling feel. With frame‑lock mechanism and caged ceramic ball bearings, the flipper‑operated deployment is ultra‑smooth, and the lock‑up stays zero‑wobble even during intensive cutting jobs.
All hardware including back spacer, pivot cap, screws and right‑side tip‑up pocket‑clip is constructed with sandblasted‑titanium for unified gray‑toned appearance and long‑term durability.
If you are searching for a rugged tactical‑grade work‑horse or a high‑end collectible folding knife, KB Navigator KB458A with premium M390 steel and well‑crafted titanium build is a fantastic choice for serious knife enthusiasts.
