KB Prism KB243D Button Lock EDC Folder – Micro Milled Titanium Handle Bohler M390 Tanto Pocket Knife with Ceramic Bearings
For EDC collectors chasing an ultra-slim, featherlight premium pocket knife with high-end steel and satisfying button lock deployment, the KB Prism KB243D stands out as a refined daily carry staple. Masterminded by designer Yuze Zhong, this compact titanium folder prioritizes minimal weight, smooth action, and elite cutting performance, all backed by a comprehensive lifetime manufacturer warranty.
At its heart sits a sharp 3.54-inch tanto point blade crafted from legendary Bohler M390 super stainless steel. Each blade undergoes strict vacuum and cryogenic heat treatment to reach HRC 60–62 hardness, delivering exceptional edge retention and outstanding corrosion resistance ideal for all-day urban carry. The flat-ground plain edge is sharpened to a precise 15°–20° angle, excelling at slicing cardboard, packaging, and light utility tasks. A uniform bead blast blade finish eliminates glare and hides minor scuffs, while the thin 0.12-inch blade thickness balances rigidity and cutting agility.
Every structural component is precision machined from lightweight grade titanium. The handle features unique micro-line milling paired with sandblasting, creating subtle tactile texture that prevents slipping without adding bulk. Titanium back spacer, pocket clip, pivot cap, and all screws receive matching bead blast finishing for a seamless monochromatic silver aesthetic. Its innovative button lock mechanism delivers secure blade retention with zero play during use, paired with caged ceramic ball bearings at the pivot for friction-free, lightning-fast ambidextrous opening.
Weighing merely 2.05 oz (58 g), the KB Prism KB243D is one of the lightest full-titanium button lock folders on the market. With an overall length of 8.27 inches, it fits discreetly inside pockets via its tip-up right-side titanium clip. The slim 0.39-inch handle thickness avoids bulky pocket bulge, making it perfect for minimalist carry fans.
Combining world-class M390 metallurgy, full titanium lightweight build, unique micro-milled detailing, and reliable button lock functionality, the KB Prism KB243D is a sophisticated high-performance EDC knife tailored for enthusiasts who value portability and premium craftsmanship.
