The need to break a side or rear window in your car rarely arises… but when it does, it really does.
The GTFO Wrist Strap from OscarDelta is a glass breaking tool that can be worn on your wrist so that it is always with you. It consists of a length of shock cord with a tungsten carbide bead.
To use the GTFO Wrist Strap, remove it from your wrist. Hold the shock cord in one hand and the bead in the other. Stretch the shock cord and release the bead so that it strikes the window. This simple design allows the user to generate high velocity for the bead in a confined space.
These are also available at USA based dealer, Vigilant Gear.
