The Ruike D191-B Folding Knife is a robust and elegant folding knife, perfectly suited for a wide range of outdoor, sporting, hunting, and fishing activities. Crafted with precision, this knife combines high-quality materials with thoughtful design to deliver reliable performance. The handle features a neatly stonewashed metallic finish, complementing the blade's brush finish for a sophisticated look. Its ergonomic design ensures a comfortable and secure grip, making it an excellent choice for everyday carry (EDC) or more demanding tasks in the field.

A standout feature is the enhanced frame lock, which includes a "Beta Plus" safety system. This innovative mechanism provides superior security, preventing accidental blade closure and allowing the folding knife to function with the stability of a fixed-blade knife when engaged, ideal for harsher conditions.

• Sandvik 14C28N Stainless Steel, Cryogenic Treatment
  Sandvik 14C28N is a martensitic stainless chromium steel with a chemistry optimised for high quality professional knife applications that demand exceptional edge sharpness, edge stability, and corrosion resistance. Ruike intensively processes the 14C28N using quenching and cryogenic treatment, achieving an ideal hardness of 58~60 HRC.
• G10 Knife Handle Front & 420 Stainless Steel Handle Back
  The G10 scale offers good wear resistance and provides a firm grip. The other half of the handle, made from 420 stainless steel, enhances the strength and toughness of the overall handle structure. The 420 stainless steel also features high standards in toughness, abrasive resistance, and corrosion resistance.
• "Beta Plus" Safety Lock
  Deploying the blade and pushing the "Beta Plus" lock up transforms your pocket-size folding knife into a fixed-blade knife, enabling it to handle more rigorous conditions with increased reliability and security.
• Thrust Roller Bearing Washer
  The built-in lubricated balls are crafted from specialised high-carbon chromium bearing steel and are finely machined. These balls provide excellent hardness, wear resistance, and fatigue durability, ensuring smooth blade deployment.
