The term "blade out" when referring to folding knives means that the blade of the knife is positioned outside of the handle when the knife is in the folded or closed position. In other words, the cutting edge of the blade is exposed and visible when the knife is folded.
Whether "blade out" folding knives are legal in all states depends on the specific laws and regulations of each state. Knife laws can vary significantly from one state to another, and some states may have restrictions on the carry and possession of certain types of knives, including folding knives.
In some states, "blade out" folding knives may be considered "automatic knives" or "gravity knives," which are subject to stricter regulations or outright bans. An automatic knife is a type of folding knife that can be opened with one hand through a button, switch, or other mechanism, while a gravity knife uses gravity or centrifugal force to open the blade with a flick of the wrist.
It's crucial to familiarize yourself with the knife laws in your specific state and locality to ensure that you are in compliance with the regulations. Some states have restrictions based on blade length, type of opening mechanism, and whether the knife is concealed or openly carried.
If you have any doubts about the legality of carrying a "blade out" folding knife in your area, it's best to consult local law enforcement or legal authorities for clarification. Additionally, always exercise caution and responsible knife ownership, regardless of the knife's legal status, to ensure the safety of yourself and those around you.
