Functional Analysis

CNC Precision Advantage

• Vertical wire-cut inner hex achieves ±0.1mm tolerance for reliable screw/bolt engagement (tested to 50Nm torque).
• Double-stamped edges increase yield strength by 18% vs. single-stamp designs (per ASTM E8 tensile tests).

Tactical Defense Optimization

• 90mm length aligns with palm ergonomics:
  • 70–100mm: Ideal strike range for pressure-point targeting (per FBI close-combat guidelines).
• 3.8mm thickness balances penetration force (∼300N) and pocket-friendliness.

Stone-Washed Durability

• Ra 0.8μm surface roughness from water polishing reduces snagging risk during drawstrokes.
• Stone washing extends corrosion resistance to 500+ hours in 5% saline environments (ASTM B117 salt-spray compliance).
