Why Choose Plastic Self-Defense Knives?

Plastic knives offer lightweight, discreet carry options for personal protection. Made from reinforced ABS plastic, these tools maintain a functional edge while being easy to carry in pockets, purses, or on keychains. Disguised designs, such as brush knives and keychain knives, provide low-profile protection.

Plastic Knife Options:

  • Keychain Knives – Compact blades that attach to keys (My Kitty, Shar-Key)
  • Comb Knives – Disguised as hair combs for discreet carry
  • Brush Knives – Hidden blade designs that look like grooming tools
  • Credit Card Knives – Wallet-sized folding knives
  • Push Daggers – Palm-grip plastic striking tools

Key Features:

  • Lightweight ABS or reinforced plastic construction
  • Sharp edge retention for emergencies
  • Disguised designs for low-profile carry
  • Easy to conceal in everyday items
  • Some models include additional features (window breakers, bottle openers)

CRITICAL LEGAL WARNING: Plastic knives are ILLEGAL to carry in many jurisdictions. Even if legal to own, carrying concealed knives (plastic or metal) may require permits. Some states specifically ban "undetectable" knives. These knives are PROHIBITED in all airports, government buildings, schools, and secured facilities regardless of material. Check your state and local laws before purchasing. Attempting to carry these through security checkpoints could be a federal crime.
