Pocket Knife laws in Washington

In Washington State, the possession and carrying of pocket knives are generally permitted. There is no state law prohibiting the possession of switchblade knives or gravity knives, nor are there prohibitions on the blade length of knives that can be carried. However, concealed carry permits are issued for firearms, not knives, and while there is no specific state statute prohibiting the concealed carry of any knife, it is important to note that Washington does have laws against carrying a concealed deadly weapon. A knife *could* be considered a deadly weapon depending on the circumstances and how it is used. Local ordinances may impose additional restrictions on knife possession and carry within specific municipalities. While state law does not explicitly define prohibited knives for general carry, restrictions can arise under broader laws concerning deadly weapons, or through local ordinances. For example, RCW 9.41.270 addresses prohibited weapons and could potentially apply to knives under certain circumstances, particularly if they are possessed with intent to use them unlawfully against another person, or if they are disguised. Violations of concealed deadly weapon laws can result in gross misdemeanor charges, leading to potential jail time of up to one year and fines of up to $5,000. It is crucial for individuals to be aware that specific locations, such as schools (RCW 9.41.280), courthouses, and other government buildings, often have explicit prohibitions against carrying knives, regardless of blade length or carry method. Travelers and residents in Washington should be aware that while carrying a pocket knife is generally legal, "concealed" carry of any object that could be construed as a deadly weapon can lead to legal scrutiny. Open carry of a pocket knife is typically permissible, but concealed possession, especially of larger knives, could be problematic if intent to use as a weapon can be inferred. It is advisable to familiarize oneself with the specific laws of any city or county being visited, as local regulations can vary significantly. Additionally, awareness of the restrictions in secure zones like schools, federal buildings, and airports is essential to avoid legal entanglements.
