The Gray Bearded Green Beret company offers an inconspicuous set of tools that can be useful in life-threatening situations.
The Escape and Evasion Kit contains tools that allow you to free yourself from potential unlawful imprisonment - the manufacturer emphasizes the word UNLAWFUL. And so the toolbox contains a 6-part lockpick set for Titanium Locks, a Kevlar cord with a strength of 200 pounds (about 91kg), two handcuffs keys - made of plastic to reduce detection, an "escape" capsule measuring 19.3 mm x 6, 6mm and a weight of 0.3 grams and a few other "trifles" allowing to pave the way for an escape in the event of kidnapping or detention against our will.
The kit can be purchased (only in the US - information from the manufacturer's website) for $ 79.99.
The manufacturer emphasizes that the kit should be used only in the event of unlawful imprisonment.
