Pocket Knife laws in New Hampshire

In New Hampshire, the possession and carrying of pocket knives are generally legal. While there is no specific state statute that explicitly prohibits or narrowly defines pocket knives for general public carry, laws governing dangerous weapons and prohibited places are relevant. New Hampshire RSA 159:1 defines a "deadly weapon" as "any substance or object which, when used in the ordinary manner contemplated by its design and construction, will or is capable of causing death or serious bodily injury." While a pocket knife does not automatically fall under this definition, its use in a threatening manner could lead to charges under this statute. Critically, RSA 159:4 prohibits the possession of dangerous weapons in state buildings, courthouses, and correctional facilities. Regarding penalties, a violation of RSA 159:4, which prohibits possessing dangerous weapons in specific prohibited places, can result in a fine of not more than $1,000 or imprisonment for not more than one year, or both. If a pocket knife is used in the commission of a crime or to threaten another person, it could be considered a deadly weapon, leading to more severe assault charges, which are classified as misdemeanors or felonies depending on the circumstances and degree of injury. It is important to note that while general possession is legal, specific locations may have bans on knives. Schools, for instance, have strict prohibitions on carrying weapons, including knives, under RSA 193:6. Travelers and residents should be aware that while open carry of a pocket knife is generally permissible, concealed carry laws can be more nuanced and may vary by local ordinance. While state law does not explicitly regulate the blade length for open or concealed carry of pocket knives, it is prudent to exercise caution with larger blades, as they may attract more scrutiny under broad dangerous weapon statutes. Always verify local municipal ordinances, as some cities or towns may impose additional restrictions not covered by state law.
