yes
I'm not for sure but i think they might be illegal in the state of Colorado. Please correct me if i am wrong.
a 7 inch blade
In order for a lock-back knife to be the legal size, the blade cannot be longer than seven inches. However, carrying a lock-back knife in public is still considered illegal regardless of its size.
Based on the law, pocket knifes seem to be the ONLY knife you can carry in public, but only in defense.
4 inches
i have know idea.......i was hopeing you would know......hahahahahahahahahahahahahahahahahahahah
it is legal to carry a knife there but not switchblade or butterfly.
Ross Lynch does carry a pocket knife, but doesn't talk about it.
Yes switchblade's are illegal in Colorado as is any knife that is assisted opening such as a gravity knife like the butterfly knife or is assisted with a spring or lever. This is not completely true. A knife that is "spring assisted" is legal as long as you have to have direct contact with the blade to open it (such as those that have a small nub on the back of the blade, or those that have a thumb nub), while "spring loaded" or "automatic" (as stated above) are illegal. Many knife makers such as Kershaw have spring "assisted" knives that are completely legal in Colorado.
No, it is illegal to carry a butterfly knife in Iowa. Iowa law prohibits the carrying, display, or use of such knives.
The blade on a concealed knife cannot exceed four inches.
