Gravity knife
A gravity knife is a folding knife which can be opened solely by the force of gravity or centripetal force. Also implied is usually some kind of locking mechanism to keep the blade locked in place once opened. A release lever releases the blade whilst folding back. Many such knives are spring loaded for easy release (opening) of the blade.
