Automatic OTF Knives

OTF knives use an automatic mechanism to extend the blade out the front with a push of a button or slide of a switch. Many models now come with a double action mechanism that both extends and retracts the blade with the same button using just one hand. Single action OTF knives extend the blade automatically with the push of a button but generally require two hands to return the blade inside the knife manually. Automatic knives have become legal in most states but there are still some where they are not permitted or have restrictions, please see our Automatic Knife Laws page for reference on restrictions.
