There is no such thing as centrifugal force. There is centripedal force, but that's not how knives open.

A number of knife laws use language related to "centrifugal force." I have never heard of using a physics based argument that the phrase is meaningless, or just plain wrong. However, the more strikes against the law as written, the better the chances of getting it repealed.
If you can show up at the hearing and explain to the legislators in simple language non-scientists can understand, that the language the law uses does not describe knives that flick open on a pivot, or that the language is unfairly vague, that could really help.
In my opinion, in order for this law to be repealed Democrats will need a reason to support the bill. Colorado Democrats hate weapons, and they hate self defense. A focus on issues they like is needed. They like due process. They dislike laws that give the police a reason to hassle minorities. Repealing unfairly vague laws makes sense to Democrats (and to most Republicans also, but Colorado Republicans are OK with weapons and self defense, for the most part anyway. So that argument can suffice for them to support it). An argument that the language the law uses is vague because it describes a force that doesn't exist in the science of physics could make sense to Democrats.
