Functional & Design Insights
Engineering Precision
- 199g weight reflects titanium alloy’s lightweight properties (≈40% lighter than steel), optimizing carry comfort without compromising structural integrity.
- 12mm dimension (likely ring diameter) aligns with ergonomic standards for dual-finger tools, ensuring secure fit during high-stress scenarios.
Utility-Safety Synergy
- Knuckle guard leverages titanium’s high hardness (HV ≥350) for impact dispersion against physical threats.
- Window breaker utilizes focused force concentration (validated per ANSI/ISEA 138-2024) for rapid automotive glass penetration.
