Spring Assist Knife Laws - Legal In US, UK, CA, & AUS

What are the Legal Definitions?
Switchblade
A switchblade (also known as automatic knife, switch, or, in British English flick knife) is a type of knife with a folding blade that springs out of the grip when a button or lever on the grip is pressed. There are two basic types: side-opening and out-the-front (OTF). A side-opening knife's blade pivots out of the side of the handle (in the same manner as an ordinary folding knife). An out-the-front knife's blade slides directly forward, out of the tip of the handle. Many OTF (out-the-front) knives work with a dual-action mechanism that enables the user to extend and retract the knife in one press of the finger, with no cocking or priming action. However, some OTF (out-the-front) knives are single action, and require the user to manually retract the blade. A wide variety of blade designs may be found on switchblades, but the most common is the Italian stiletto style seen often in movies. However, the switchblade should not be confused with the butterfly knife (balisong), assisted-opening knife, or the non-automatic stiletto.
Assisted-Opening Knife / Spring-Assisted Opening Technology
A spring-assisted knife is a knife that when you push on the thumb stud to open it a spring takes over and propels the blade open. Spring-assisted knives make a great alternative to automatic knives. A Spring / Torsion assisted knife is a type of knife which uses a spring assisted mechanism behind the blade. They open by the ambidextrous thumb stud on the blade with a slight bit of pressure. They are commonly confused with switchblades, but have one main difference. While a switchblade can be opened usually with the push of a button within the handle, the user of a spring-assisted knife must apply slight pressure to the thumb stud and the spring/torsion assisted mechanism does the rest. Once the knife has been opened about one-quarter of the way (45°), the mechanism will open the knife the rest of the way. A/O knives are Assisted - Opening which are also Spring - Assisted knives.

US Assisted Knife Law
CALIFORNIA is the basis of all law due to it being typically the hardest and most progressive

California State Senator Betty Karnette of the 27th District is the author and who is responsible for Bill SB 274 and the legalization of Spring Assist Knives.

Senator Karnette realized that Spring Assist Knives are extremely functional tools by law-abiding citizens and that these knives serve an important utility to many knife users, as well as firefighters, EMT personnel, hunters, fishermen, and others who utilize one-handed opening knives.

Spring Assist Knives are intended to save lives while an EMT, Firefighter, or Law Enforcement Officer is trying to get you out of an automobile accident or any other viable problem. They have saved skydivers lives that had to cut parachute lines. They have saved countless fishing poles when a line is needed to be cut. They are also essential to handicap individuals whom happen to have one arm. Special Thanks to Senator Betty Karnette is in order because if it were not for her we would loose more of our rights in this country and also not have tools that are lifesaving instruments.

[Th232]

Small note to add, while in Australia, AOs are legal (barely), Australian customs has issued a ruling that they will consider AOs to be the same as switchblades, and will thus confiscate/return/destroy any that they find.

So, legal to own, illegal to import without a permit.

Your title is somewhat deceptive and misleading, AO's are "Legal in the US" only in the sense that there is no Federal law against them. Some states do classify them as switchblades, and in others, like New York, while they are legal to buy and sell (at least outside of New York City), you may very well be charged with possession of a switchblade if you are stopped while carrying one.

I suspect that their "legality" in the other countries you mention is, as Will pointed out regarding Australia, tenuous at best.

WOW it's not even April 1st. I'll have to look into this.
