Amarillo, TX...Potter County. Local retail stores have been advised by the Amarillo Police Department they must stop selling the Kershaw speed safe knives. After a recent arrest, the county attorney has deemed they are considered "switchblades". The county attorney is Sonya Letson. Her department has refused to hear arguments from knife experts and even local law enforcement that these knives really aren't switchblades. Anyone who can read can easily tell that these knives don't fit the definition under the federal switchblade law (I believe it was the August issue of Blade magazine that outlined this same point). Some retailers have removed all of the assisted opener knives from their shelves (Sog flash, Myerco). If you would like to contact Sonya Letsons office let me know and I will post her department's contact information.
