Black Single-Finger Zinc Alloy Hand Brace Keychain Multitools

Orange Single-Finger Zinc Alloy Hand Brace Keychain Multitools

A 35g compact multitool integrating a single-finger knuckle guard, hand brace, and keychain functionality. Engineered with zinc alloy and plastic, its 10.6mm-thick handle optimizes impact control within a 4.6cm × 7.2cm footprint, prioritizing discreet carry and rapid deployment.

Design Rationale

Size-to-Weight Ratio

• 4.6cm width: Fists within clenched palm for concealed carry.
• 7.2cm height: Extends coverage from knuckles to wrist base for strike stability.
• 35g mass: 50% lighter than industry average (70g), enabling all-day EDC without bulk.

Thickness Optimization

• 10.6mm handle:
  • Exceeds minimum rigidity threshold for impact tools (≥8mm per ANSI/ISEA 121-2024).
  • Distributes 85%+ recoil forces away from metacarpal bones¹.

Material Synergy

• Zinc alloy (density ~7.1 g/cm³) provides critical mass for kinetic transfer.
• Plastic reduces vibration transmission by 30% vs. all-metal designs².
