Abstract
A pocket knife with lock design is disclosed. This foldable knife has a pivot joint, a blade controlled by the pivot joint, a safety lock corresponding to the side wall of the blade, and a resilient pin, wherein the back end of the blade has a shoulder and a pin catch. The safety lock has a spring tab with a raised head that is moved to touch the back of the blade after the blade is pulled out from the handle by a predetermined angle. The resilient pin is placed in a chamber within inner space of the handle, where one end pushes against the shoulder of the blade for supplementing the driving force to pull out the blade to an open position.
