Hidden Blade Knife Types
Every product in this collection conceals a blade inside an everyday object — the disguise is the primary carry advantage. The functional comb with a hidden blade has a 3.5 inch blade that slides from the comb body — carries naturally in a back pocket or bag alongside actual grooming items. The pen knife looks and carries like a standard ballpoint pen with pocket clip — the most office-appropriate disguise in the collection with a 2.13 inch blade. The lipstick knife uses a cosmetic tube profile with a 1 inch blade — fits in a purse or makeup bag without standing out. The hair brush knife is a functional brush with a 4.25 inch blade concealed in the handle — the longest blade in the collection. The credit card knife is credit card sized and fits flat in a wallet — unfolds into a usable blade for utility and emergency use.
What to Know Before Buying
Blade deployment varies by model — twist, slide, or pull mechanisms depending on the disguise type. Most models serve as actual working versions of the object they mimic: the comb functions as a comb, the pen writes, the brush brushes. That dual function keeps the disguise convincing during regular use rather than sitting untouched. Blade lengths range from 1 inch on the lipstick knife to 4.25 inches on the hair brush knife — check local blade length restrictions before purchasing.
