Full-Auto Knife
Common Use Names:
Flick Knife, Switchblade, Automatic Knife
Cited:
The Restriction of Offensive Weapons Act (1959)
Prohibits:
Manufacture, import, sale or hire, or offer of sale or hire, or lending or giving to any other person.
Legal Definition:
Any knife which has a blade which opens automatically by hand pressure applied to a button, spring or other device in or attached to the handle of the knife.
Common Misconceptions:
Rolox actions, Speedsafe actions (commonly referred to as semi-automatic knives) are not full-auto knives. Whilst they open in a similar fashion, they do not meet the criteria of the Restriction of Offensive Weapons Act (1959), as the device required to be operated to deploy the blade is attached to the blade itself, and therefore is not in nor attached to the handle of the knife.
