The GTFO-Wrist-Strap® facilitates escape and rescue via the vehicle side or rear windows when seconds matter.

Compact, wearable, and purpose-built for rescue situations. Just a single strike directed from the wrist strap is enough to break glass!

To deploy simply remove wrist strap, place around thumb and forefinger, pull back on the Ballistic-Striker-Bead® and release…

The Mission

Enhance the performance of a discreet and wearable rescue tool capable of destroying tempered glass.

The first generation (2019- 2023) GTFO-Wrist-Strap® 1.0 featured a MSB-TC (Micro Striker Bead – Tungsten Carbide). Since 2023 it has been replaced with the GTFO-Wrist-Strap® 2.0 that features the Ballistic-Striker-Bead®.

From Concept > Production

The Ballistic-Striker-Bead® is a premium product manufactured to a high specification:

  • No rough or sharp edges
  • Polished for a smooth finish  
  • Resistant to oxidation 
  • Non-slip texture to aid deployment

Hits Different

The primary function of the Ballistic-Striker-Bead® is to impact and destroy tempered glass using kinetic energy and force to aid rescue from a vehicle via the side or rear windows.

Trust The Science
The hardness of the Ballistic-Striker-Bead® (Hv30 1750) exceeds the core hardness of armour-piercing ammunition (Hv30 1450) , so you only need a small amount (1.2g) to deliver the ‘impact, energy and work’ to destroy tempered glass on the first strike!

Impact and Work

Work occurs when a force is applied to move an object a certain distance. Therefore, work is equal to force multiplied by distance: 

W=Fd

Impact and Energy
Energy is defined as the ability to do work. During an impact, an object’s energy is converted into work. The energy of a moving object is called kinetic energy, and is equal to one half of the object’s mass times the square of its velocity: 

 KE=\frac{1]{2}mv^2

Shock and Awe

We only use the best quality shock-cord from a family owned business with a rope-making tradition going back to 1856.

  • Braided Poly Outer
  • Natural Rubber Core
  • UV Stabilised

The GTFO-Wrist-Strap® features our End User Adjustment System for a custom fit – not too tight, not too loose…just right!

The design of the GTFO-Wrist-Strap® allows for a low-profile handcuff key to be added or removed.

The AHK-rf (Advanced Handcuff Key – retrofit) works just like any other AHK3 to counter the security features found on high security handcuffs (key blocking blade, large keyway pin, deep set keyhole etc.) The AHK3 has a full depth slit in the key flag to counter the stainless-steel security plate on ASP High Security handcuffs.

The Twistlock secures the AHK3-rf onto strap.

Note: there is no requirement to remove the AHK3-rf from the GTFO-Wrist-Strap® to open handcuffs. Simply remove the wrist-strap from your wrist, pull the cord into the slot of the AHK3-rf and then insert into the key-way.

To remove the AHK3-rf you will require tools (needle nose pliers and a safety pin or r-clip). Insert the pin through the two holes located at the top of the AHK3-rf and then rotate the Twistlock to the open position with needle nose pliers. Extract the shock-cord from the key slot.

The AHK3 works on the Key Operated Nylon Restraints (make sure the key is fully inserted) and the following handcuffs plus more that share the common key-way:

  • ALCYON
  • ASP
  • CLEJUSO
  • HIATTS
  • KYOUNG CHANG
  • PEERLESS
  • RALKEM
  • RUSSIAN BRS-1
  • SMITH & WESSON
  • TCH
  • UZI
  • WALTER
  • YUIL

The AHK3 also operates handcuffs that have a bent pin in the keyway that would otherwise block a standard handcuff key.

The AHK3 and AHK3-rf are made from steel that has been heat treated and chemically coated black (ChemBlack).
