clipped from: www.kniferights.org U.S. Customs & Border Protection (CBP) has proposed revoking earlier rulings that assisted opening knives are not switchblades. The proposed new rule would not only outlaw assisted opening knives, its broad definition of a switchblade would also include all one-handed opening knives and could be easily interpreted to cover most other pocket knives, even simple old-fashioned slip-joints.
Please note that CBP's interpretation of the Federal Switchblade Act forms the basis for national, state and even local law and judicial rulings in many cases. This effects bof this ruling by CBP is NOT limited to just imports. This WILL affect virtually everyone who carries a pocket knife, no matter the type!
