If you are in a place like Portland or Oregon City that restricts loaded carry by people who do not have concealed handgun licenses, you may not have a loaded firearm in your vehicle. Furthermore, if it is a handgun, it must be carried openly or "not readily accessible."
No, however, state and Federal law laws do place limits on the places where you can take a firearm- loaded or unloaded.
Depends on where you are. They are illegal in New Jersey.
Oregon is an traditional open carry state. Both State and Federal laws do place limts on where you can carry any firearm, in any manner.
If you have a handgun carry permit, definitely. The handgun carry permit covers "any handgun that you legally own or posses."
It depends on where you are, and what the weapon is. In Tennessee, for instance, basically anyone can carry a knife if it has a blade less than 4 inches long. However, to carry a handgun, you must be 21 or older and have a handgun carry permit.
Not sure what you're asking, but I'll take a stab at it. If you're asking "Is it illegal to carry a handgun," the answer is, it depends on where you are. In the U.S. some states require a permit to carry a handgun concealed, but a few don't. A few states allow you to carry a handgun openly, but most don't. Two states, Wisconsin, and Illinois, and D.C. don't issue carry permits.
Switchblades are in fact legal to posses in Oregon, although to carry it with you, in order for it to be legal, it CANNOT be concealed (this means it has to be visible). If you are under 18, be careful, it's illegal to carry.
It isn't generally illegal to carry on a boat, assuming you can otherwise legally carry a handgun, however, it may be illegal in certain locations. If you are on a federally controlled waterway, it is probably illegal, or some states may have restrictions.Added: Check the laws of your particular state. The same law applies to boats as would apply to motor vehicles on state waterways. See above answer for the answer to federally controlled waters.
No. You just get arrested or shot. It is not illegal to carry a handgun into a bank in Arizona as long as you have a permit and as long as the bank does not have a sign posted stating no guns are allowed. You will not "just get arrested" because it isn't illegal.
I think they shouldn't because if you take them away you can't protect yourself. You can't use concealed carry either.
You can not carry an unconcealed handgun in Texas with or without a license.
No
No, you may not. Federal law requires that you be 21 to own a handgun, or under adequate supervision to possess a handgun (which in this case you're neither). If discovered by law enforcement, this constitutes illegal possession of a handgun, which is taken very seriously.
