With the appropriate skills, knowledge and understanding can be used to facilitate escape from unlawful restraints and captivity using non-destructive methods. It is recommended that you have one spare SAD Tool that can be used for 'development' to explore the capabilities and potential applications of the tool. These 'special activities' require access to a set of handcuffs, heavy duty cable-ties and a budget padlock (pin and cylinder that locks on one side of the shackle).
With practice you will be able to remove handcuffs without a key (single and double/transport lock) and exploit weaknesses in the handcuff design to bypass the double-lock mechanism to allow for shimming etc. These methods can be used on so called 'high security' handcuffs that have additional features that would normally require a unique or non-standard key to operate.
With continued practice it works quicker than a key for taking off the double-lock, particularly when handcuffed to the rear.
You can also use the tool to open a budget padlock without a key and remove cable-ties using non-destructive methods.
