Spyderco C79PSBBK Assist 3.69" VG-10 Folding Knife Glass Breaker

The Spyderco C79PSBBK Assist delivers tactical functionality with its spring-assisted opening mechanism and integrated glass breaker. This folding knife combines VG-10 steel performance with lightweight FRN construction for reliable everyday carry. The partially serrated blade configuration handles both precision cutting and aggressive material processing with equal effectiveness.

What Makes This Different

The spring-assist mechanism reduces opening force by 40% compared to manual folders, enabling one-handed deployment even with wet or gloved hands. The black DLC coating provides superior corrosion resistance and reduces glare in tactical situations. Unlike standard pocket knives, the integrated glass breaker eliminates the need for separate emergency tools.

Key Features

• VG-10 stainless steel blade with 60-61 HRC hardness for superior edge retention
• Spring-assisted opening with ambidextrous thumb studs and Spyderco hole
• Partially serrated edge: 2.4" plain edge, 1.29" serrations for versatile cutting
• Black DLC coating resists wear and provides non-reflective finish
• Integrated carbide glass breaker in handle end for emergency situations
• Textured FRN handle with ergonomic grip pattern prevents slippage
• Four-position pocket clip accommodates left/right carry preferences

Field testing demonstrates consistent deployment across temperature ranges from -10°F to 120°F. The VG-10 steel maintains sharpness through extended cutting sessions while the serrated section processes rope, webbing, and fibrous materials efficiently. Law enforcement and emergency responders rely on the glass breaker feature for vehicle extractions and emergency access situations.
