Deadly Weapons & Knives


If you live in Hawaii and you want a Switchblade, you might be out of luck. Below are the laws for weapons & knives pertaining to Hawaii, given by the Honolulu Police Department.

If you still want a switch blade, a legal alternative we recommend an Assisted Opening Knife. They handle very similar to Automatic Knives, but but the laws for Auto Knives don't apply to them. As for a Balisong or Butterfly Knife, if you are trying to practice the flipping machanics of these knives, we recommend using Training Knives for practice.
