If the knife is on the inside of the pocket, it is concealed and must follow concealed carry laws. if it is on the outside, it is open carry. As long as it's lawful, you can carry it either way. I personally carry the knife on the inside of my pocket.
Based on the law, pocket knifes seem to be the ONLY knife you can carry in public, but only in defense.
All you need to do is get a knife or pocket knife and the edges of the CD you go in the middle and you go back and forward and you have cut open the CD.
Typically there is a screw or small bolt on one side of the handle, which extends through the blade. loosen that a little, and your knife will be easier to open and close. Also, you could use some grease or WD-40 to keep it nice and smooth.
no. lots of people carry pocket knives. you may not have them on planes or at schools thoughAdded: Just because a knife fits into your pocket does not make it a "pocket knfe." The type of knife also makes a big difference. Many knives that fit in a pocket are, in fact, illegal in some jurisdictions (e.g.: switch-blade knives - butterfly knives/balisongs - 'gravity' knives [those that open at the flick of your wrist] - etc).Be careful - know the law of the location you are in. Regardless of whether or not it 'clasps' together or fits in your pocket, some jurisdictions put a maximum length on the size of a concealable knife. You COULD be in violation if in those locations.ALSO -
They have a hinge muscle which is located where the edges of its shell meet. If you stick a knife in there and sever the muscle then it will open easier.
In Pennsylvania, the legal size limit for a pocket knife is under 4 inches in length when in the open position. Knives larger than 4 inches may be considered illegal if carried for purposes beyond work, education, hunting, or other lawful activities.
Give them really good reasons why you should need a weapon. And by saying that, and being a parent, I doubt you will come up with good enough reasons. If you say your friends have knives they will imagine all of you in a knife fight. Tell them you are prepared to adjust to many rules regarding where to keep it, when to use it and how to use it.
A switchblade is actually a type of pocket knife that opens quickly. A pocketknife does not always open automatically like a switch-blade, so that is the difference.
Open the wall and build a pocket. Try an encyclopedia!!!!!
Folding knives do not auto open, a folding knife would refer to a knife such as a buck knife, or swiss army knife, both of which require to be manually opened. If you are asking how to convert a folding knife or "folder" into an automatic knife, well it is possible but it would have to be enabled for conversion. For instance, a boker magnum AK74 knife may be sold without a spring for legal reasons, then to make it the automatic switchblade it was meant to be, you would have to add a spring by taking it apart. If you are asking how to open an automatic knife (i.e., a switchbalde, or spring assisted knife), then the answer is it has to be engaged with the push of a button, a switch, or a lever; doing so will allow the spring to deploy automatically given you took the safety off if it has one.
get a knife and slit its belly open
