Patent ID: 8584367

Claim:
A pocketknife comprising: a handle having an inside end, an outside end, a seat side, an open side being opposite to the seat side, and the handle further having a cavity defined through the open side; an opening defined through the seat side and communicating with the cavity; and an assembling slot defined in the handle; a blade mounted pivotally on the inside end of the handle, selectively accommodated in the cavity or extending laterally and having a proximal end mounted pivotally on the inside end of the handle; and a point being opposite to the proximal end; an assistant assembly mounted in the handle, assisting to extend the blade out or retract the blade in the cavity of the handle and having a dial mounted rotatably in the assembling slot of the handle, mounted securely on the proximal end of the blade so that rotating the dial synchronously pivots the blade; a biasing lever mounted slidably and being capable of swaying in the assembling slot of the handle, mounted pivotally and eccentrically on the dial and having a mounting end mounted pivotally and eccentrically on the dial; and a stem being opposite to the mounting end; and a spring mounted around the stem in the assembling slot of the handle and biasing the mounting end of the biasing lever toward the dial and near the seat side so that the dial is forced to rotate in a rotational direction tending to retract the blade in the cavity when no external force is applied; wherein manually rotating the dial reversely to move the mounting end of the biasing lever toward the open side of the handle extends the blade out of the handle; and a locking assembly mounted on the handle and selectively holding the pocketknife in an unfolding configuration; wherein the handle further has two windows defined oppositely in the handle; and wherein the dial extends out of the windows.
