That is actually an opinion, not a fact.
The Connecticut General Statutes prohibit "...
any switch knife, or any knife having an automatic spring release device by which a blade is released from the handle, having a blade of over one and one-half inches in length..."
The statutes make no mention of assisted opening knives. However, they do not define a "switch knife". The wording following the comma after switch knife would seem to be a definition of a switch knife, but the comma indicates that the legislature considered them to be separate entities.
See
this post in the Knife Laws sub forum for additional information.
One of the guys who works for me recently confiscated an assisted opening knife but did not arrest the person who was carrying it. He later showed the knife to me. I explained that it was an assisted opening knife, and found out that he had never heard of one. I explained the difference between a switch blade and an assisted opener, and told him that I did not consider the knives to be illegal. He respectfully disagreed. Since the statutes involved are admittedly ambiguous, I am trying to obtain an opinion from the States' Attorney for our area. (Despite the fact that they seldom want to commit to any firm opinions.) If I am able to get a ruling, I will post it in the Knife Laws forum.
Checking the AKTI website last night, I discovered that they were able to get an
amendment to the Federal Switchblade Act that explicitly exempts assisted opening knives from the laws prohibitions (see below). I will provide this information to the States' Attorney when I try to get his opinion.
The change to the act includes language stating that knives fitting the following description are not switchblades;
a knife that contains a spring, detent, or other mechanism designed to create a bias toward closure of the blade and that requires exertion applied to the blade by hand, wrist or arm to overcome the bias toward closure to assist in opening the knife.*
(I noticed that the definition is followed by an asterisk, but I was not able to determine what it referred to. There don't seem to be any corresponding asterisks on that page.)
