KB KNIVES Protocol KB419C Frame‑Lock Folder – Full DLC‑Coated Titanium Handle, 3.35‑inch DLC Bohler‑M390 Tanto‑Point Knife for Tactical and EDC Use
Created by Panurin Design, the KB Protocol KB419C delivers a sleek tactical‑style design combined with high‑end cutlery‑grade performance for both tactical‑oriented users and everyday‑carry lovers. Made in China and covered by a lifetime warranty, this ambidextrous‑friendly folder is built for heavy‑duty daily‑cutting, outdoor‑jobs and light tactical scenarios.
Its core performance comes from a 3.35‑inch Bohler M390 tanto‑point blade. The sharp‑angled tanto profile offers outstanding piercing and slicing capability, well‑known for tactical‑style applications. Each blade undergoes strict vacuum and cryogenic heat‑treatment to hit stable HRC60‑62 hardness. The flat plain edge is factory‑sharpened at 15‑20 degrees for consistent cutting power. A full DLC black finish shields the blade from fingerprints, abrasion and rust without weakening the steel after heat‑treatment, unlike many mass‑produced knives. When fully opened, the total length reaches 7.72 inches while the weight is 4.24 oz (120 grams), bringing a solid‑built feel without being bulky for pocket‑carry.
The whole handle is milled from solid‑grade titanium with uniform DLC‑black coating. Horizontal machined grooves on both sides increase friction and offer a comfortable, non‑slip grip. At 0.51‑inch thickness, the titanium frame keeps a balanced profile, neither overly slim nor bloated for long‑time holding. Under the frame‑lock structure, caged ceramic ball‑bearings ensure ultra‑smooth blade deployment and zero‑play lock‑up even during intensive cutting work.
All hardware components including back‑spacer, pivot cap, fastening screws and right‑side tip‑up pocket‑clip adopt DLC‑coated‑titanium material. The unified dark‑toned finish delivers a minimalist tactical aesthetic and reliable long‑term service life.
Whether you need a dependable tactical‑grade work‑horse or a refined daily‑carry companion, the KB Protocol KB419C with premium M390 steel and all‑titanium build will exceed your expectations. It perfectly blends rugged functionality with a modern under‑stated look for EDC and tactical‑knife enthusiasts.
