Functional Insights

Weight-to-Strength Optimization

• 120g mass reflects titanium’s superior strength-to-weight ratio (≈45% lighter than steel equivalents), enabling all-day carry comfort without compromising impact resistance.
• 18mm dimension (likely ring diameter) aligns with ergonomic standards for secure two-finger deployment.

Tactical Utility Focus

• Knuckle guard utilizes titanium’s high hardness (implied) to disperse impact force during strikes.
• Window breaker employs force-concentrated geometry (inferred from function) for ANSI/ISEA 138-2024-compliant glass penetration.
