Ultra-Thick 16mm Polymer Engineering

The 16mm thickness is exceptional for polymer knuckles:

• Maximum for Polymer: Thickest polymer knuckle available
• Exceptional Structural Integrity: Ultra-thick profile provides serious strength
• Superior Palm Support: Extreme thickness distributes force across entire hand
• Enhanced Finger Protection: Thick profile shields all four fingers
• Engineering Achievement: Combining 16mm thickness with 70g weight requires advanced design

Ultra-Lightweight 70g Advantage

At only 70g, this showcases polymer's extraordinary properties:

• 87% Lighter Than Steel: Equivalent steel would weigh 550g+ - nearly 8x heavier
• Practical Ultra-Thick: Only advanced polymers make 16mm viable at 70g
• All-Day Comfort: Light enough for comfortable extended carry
• Quick Deployment: Minimal mass allows instant access
• Forget You're Carrying It: Negligible weight despite massive thickness

Anti-Slip Grooves Design

The textured grip pattern provides exceptional retention:

• Enhanced Grip Security: Grooves prevent slipping in wet, sweaty, or gloved conditions
• All-Weather Performance: Maintains grip in rain, snow, or extreme conditions
• Tactical Advantage: Positive retention ensures control during use
• Comfortable Texture: Grooves provide grip without being abrasive
• Integrated Pattern: Molded into surface - won't wear off

Non-Metal Security Advantage

Zero metal content provides unique capabilities:

• Passes Security Check Machine: Non-metal material passes through metal detectors
• X-Ray Transparent: Appears differently than metal on X-ray screens
• TSA-Friendly: Non-metallic composition for security screening
• Non-Conductive: Safe around electrical equipment
• Non-Magnetic: Won't interfere with electronics
• Corrosion Immune: Never rusts or corrodes

Fine Polishing Quality

Despite anti-slip grooves, surfaces are finely polished:

• Smooth surfaces for comfortable handling
