When shopping for a high‑performance folding knife, steel selection separates standard work‑a‑day tools from collector‑worthy pieces. KB turns to Crucible CPM S90V powder steel for its premium offerings, answering the demand from seasoned knife users who want blades that stay sharp session after session.
          CPM S90V gains its legendary performance from dense vanadium‑rich carbides created through powder metallurgy manufacturing. KB does not simply use raw S90V stock; every blade receives professional vacuum and cryogenic heat treatment to unlock the steel’s full potential. The result is outstanding wear resistance, letting the knife hold its edge through heavy‑duty cutting tasks that would quickly dull ordinary stainless steel. It also offers great rust resistance, holding up against sweat, damp weather and everyday pocket exposure.
          It is important to understand S90V’s practical trade‑off. Its extreme hardness means it cannot be sharpened as rapidly as 14C28N or AUS‑10. This steel is intended for users who prioritize extended edge life over fast field re‑profiling. KB complements these high‑end blades with precision‑crafted titanium handles, often enhanced with custom anodization, micro‑milling or carbon‑fiber inlay details. Caged ceramic ball bearings deliver effortless flipper opening, paired with robust lock structures and reversible ambidextrous pocket clips for versatile carry.
          Covered under KB’s lifetime warranty, S90V‑equipped folders are built for dedicated EDC fans and collectors. If you prefer fewer sharpening sessions and uncompromising cutting durability, KB’s CPM S90V models deliver genuine super‑steel capability in a pocket‑friendly package.
