Why Plastic Self Defense Knives and Keychains
Every product in this collection is made from hard ABS plastic — impact resistant, as strong as comparable metal designs for striking use, and completely metal-detector friendly. No metal components means these pass through security screening where metal self-defense tools would be flagged. The collection covers two categories: plastic striking keychains designed for a fist grip, and a disguised plastic knife concealed in a hair brush handle. All are lightweight enough for keychain carry without adding noticeable bulk.
Plastic Striking Keychains
Four designs use the same finger loop and fist grip principle with different profiles. The My Kitty uses cat ear tips positioned between the fingers — available in six colors including glow in the dark, made in the USA. The Brutus Dog uses the same finger loop design in a bulldog profile. The SHAR-KEY fits over the fist with three distinct striking points in a shark profile. The Heart Attack uses a heart-shaped handle grip with a pointed tip extending from the fist.
Plastic Hair Brush Knife
The Hair Brush Knife is a fully functional hair brush with a 4.25 inch ABS plastic blade concealed in the handle — the longest blade in the collection and the only product here that functions as an actual knife rather than a striking tool. The plastic blade passes metal detectors. Available in three colors.
Legal Warning
Plastic knives and striking keychains are restricted or prohibited in many jurisdictions. Some states specifically ban undetectable knives regardless of material. These products are prohibited in all airports, government buildings, schools, and secured facilities regardless of material — attempting to carry them through security checkpoints could constitute a federal crime even if no metal detector alert is triggered. Always verify your state and local laws before purchasing or carrying any product from this collection. Buyer assumes full legal responsibility for possession, carry, and use.
