Armed Self Defense

In some countries, it is legal to use or carry weapons (for example knives, firearms or batons) for purposes of self-defense. In other countries, this may be illegal or may require a license, or some items may be legal to carry without a license, while others, most commonly firearms, are not. Limitations on the use of weapons for personal defense are a source of controversy in some countries, pitting self-defense rights against efforts to combat violent crime via restricting access to common weapons.[citation needed]

Everyday objects, such as baseball bats or aerosol spray cans, can also be used as improvised weapons for self-defense, but are not likely to be as effective as purpose built weapons. Some non-lethal weapons as the Kubotan have also been built to resemble everyday objects, such as keychains.[3]

Pepper spray and personal stun guns are non-lethal self defense alternatives, which are legal in some countries. Pepper sprays can have a range between 5–20 feet, and act by delivering a spray or foam containing highly irritating chemicals. Handheld stun guns operate by delivering an incapacitating electric shock, and must actually come in contact with the assailant to be effective, with the exception of tasers which use gas-propelled barbs connected to the taser by conductive wire to deliver the shock.
