Sizing Guide

The oversized 28mm × 22.8mm oval finger hole is designed for larger hands and accommodates most adult fingers comfortably, including use with tactical gloves. This is one of the largest single-finger knuckle designs available - ideal for users who find standard 23mm holes too tight.

Ceramic Glass Breaker Technology

The embedded ceramic bead is specifically engineered for emergency glass breaking. Ceramic's extreme hardness (significantly harder than steel) concentrates impact force into a tiny point, allowing tempered automotive glass to shatter with minimal force. This makes the tool invaluable for vehicle escape scenarios or emergency rescue situations.

Stonewash Finish Advantages

The stonewash finish is achieved by tumbling the steel with ceramic media, creating a uniform matte surface that:

• Hides scratches and wear from daily carry
• Eliminates glare and reflections (tactical advantage)
• Provides superior grip texture compared to polished finishes
• Develops a unique patina over time
