If you have a licence, everything is fine, but I do not think there are knife licences, just firearms licences. However, you can legally have a knife larger than 3.5″ in your car. The melodrama created by the American media about the stiletto switching blade has had its effect in Canada and Britain. The United States Switchblade Knife Act was followed by the UK Restriction of Offensive Weapons Act of 1959.  In Canada, Parliament amended the Penal Code in 1959 to include all newly produced automatic knives as prohibited weapons – prohibited from importation, sale or possession in that country. In response to complaints about the constitutionality and inconsistent application of existing laws to modern knife designs, several states such as Alaska, Arkansas, Indiana, Kansas, Michigan, Missouri, Montana, Tennessee, Texas, Virginia, West Virginia, and Wisconsin have repealed older laws against the possession or purchase of automatic blades or knives. Five states still prohibit anyone from selling, buying, owning or wearing a switch blade. Hi Dean; Thanks for the question! Technically, the answer to your question is NO, it`s not illegal if the Karambit has a blade of LESS than 3.5 inches. However, I would always do everything in my power to never be “caught” by a police officer, because anyone wearing a Karambit will look (to them) like someone who doesn`t do anything right.
This annoys me a bit because years ago, while working on a residential building I was managing, I was wearing a simple box cutter with a 1-inch blade when I had to stop at a courthouse (in Ontario, Canada). I gladly handed him over to security, but the fact that I even had such an “offensive” weapon made him hesitate to let me in! I probably wish I hadn`t shown it! Some laws can get out of control, but that`s the way it is. Keep your 3 inch karambit hidden and your consciousness should work well! Cheers, Pete It is illegal to carry a knife other than a hidden fishing or hunting knife larger than 3.5 inches. Hidden means being out of sight and close enough to be available for immediate use. It is not illegal to carry a hidden knife on your property. It is also not illegal to carry a hidden knife while driving, when carrying the knife to protect yourself. I own several Chinese wide swords and a 34-inch Jian steel spring sword that is not sharpened on sharp edges but could be used to impale Is it legal to practice/wear them on public property in Denver? As long as it`s not a fully spring-operated blade, everything will be fine. I guess you`re talking about the locking mechanism, which comes in the form of a switch on many knives, especially Gerbers, but as long as it`s not used to open the knife, there shouldn`t be a problem.
Is Bowie with cuts in his back there legal, we regularly camp there and I have a great Bowie who only wants to be legal in town when he goes down on a trip. I`m sorry to say, but after seeing the reviews of the product, it`s definitely illegal. First of all, the blade is fully supported, that is, you press a button and a spring mechanism completely opens the blade from the handle of the knife. As such, it is considered a switching blade, and as the laws show, switching blades are illegal. Sorry. Automatic knives have been legal in Colorado since 09/AUG/2017. With “Gravity Knives”. I just thought I was going to give an update. Please take a closer look at our new laws and publish them. That would be very helpful.
Thank you.Col. Thomas Mulcahy The manufacture, import, trade, use and possession of circuit knives are prohibited in Spain.  In Russia, circuit sheets (rus. автоматический нож, выкидной нож, пружинный нож) are illegal only if the length of their blade is more than 9 centimeters (about 3.5 inches) – this is an illegal weapon and there is a fine of 500-2000 Russian rubles (about 8-30 US dollars) and removal of the knife only for transport (Article 20.8 of the Criminal Code of Russia), but not for illegal purchase and possession (storage at home or elsewhere). Only self-production and sale of knives (Rus. холодное оружие) is a crime in Russia (both of these crimes are punishable by: Part 4 Article 222 and Part 4 Article 223 of the Russian Criminal Code). If the blade is less than 9 centimeters, anyone (even if people under the age of 18, with a criminal history or mental illness) can buy, possess and hide such a blade without a license (open carrying of weapons or things that resemble a weapon in human settlements; with the exception of police officers). But even in this case, it is recommended that people carry an official certificate (type approval) (which is usually in a box with a purchased knife), which proves that it is not a melee weapon and is not limited to transport, in which case knives with a length of more than 9 cm are also sometimes allowed.
    This is a view I have not yet heard. I`m a sushi chef in a small town and I prefer walking. I often carry a handful of knives over 9 inches in length in different types of transport. Can they be considered weapons? If something terrible were to happen, can I legally defend a life with them? Colorado State Bill SB17-008 reversed the Switchblade/Gravity Knife Act.
