So, I would say NO spring assisted knives are NOT LEGAL in the state of Colorado. If prosecuted, you would have to defend your case with the knife not being ballistic.

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.

We should ask one of our Colorado Senators to do the same.
