KB KNIVES Stingray KB264A Button Lock Folder – Sandblast Gray Titanium Bead Blasted M390 Clip Point Tactical EDC Knife In-Depth Review
If you crave a sleek, rapid-deployment premium folder that blends instant one-handed opening, elite blade steel and featherlight titanium construction, the KB Stingray KB264A button lock knife stands apart from standard liner and frame lock EDC tools. Co-designed by Bastards Knives and manufactured in China, this compact carry knife is backed by a comprehensive lifetime brand warranty, engineered for fast-access tactical use and all-day urban carry, with ambidextrous shaping to fit all hand sizes seamlessly.
The cutting core of the Stingray KB264A is its 3.07-inch Bohler M390 clip point blade, a top-tier stainless steel renowned for unmatched edge retention and natural corrosion resistance. Every blade undergoes professional vacuum and cryogenic heat treatment to stabilize hardness at HRC 60–62, while a flat-ground plain edge factory sharpened to a 15°–20° angle delivers clean, controlled slicing for opening packages, camping prep and light tactical cutting tasks. The uniform bead blast blade finish eliminates glare and hides minor scuffs from daily wear. Fully extended, the knife reaches an overall length of 7.17 inches, yet it weighs only 2.61 oz (74 g) — one of the lightest full-titanium button lock folders on the market, eliminating pocket drag during long shifts.
The ergonomic curved handle is precision machined from solid titanium with a consistent matte sandblast gray finish. Fine linear milling runs across the scales to add gentle non-slip grip without harsh aggressive texture, and a slim 0.47-inch handle thickness keeps the profile low-profile for discreet pocket storage. Its defining feature is the intuitive button lock mechanism, paired with caged ceramic ball bearings to deliver silky-smooth blade flicking and rock-solid lockup when open.
Every metal component matches the unified sandblast titanium aesthetic, including the backspacer, low-profile pocket clip, pivot cap and assembly screws. The titanium clip supports tip-up right-side carry only, securing the knife firmly without printing through thin pants pockets.
Combining convenient button lock deployment, industry-leading M390 steel, ultra-light titanium construction and refined ergonomic shaping, the KB Stingray KB264A is a versatile premium folder that checks every box for tactical users and discerning everyday carry collectors alike.
