Abstract
A pocketknife has a handle, a blade, an assistant assembly and a locking assembly. The handle has a cavity defined in the handle. The blade is mounted pivotally at one end of the handle. The assistant assembly is mounted on the handle, assists to extend the blade out or retract the blade in the cavity and has a dial, a biasing lever and a spring. The dial is mounted rotatably in the handle and is connected securely on a proximal end of the blade. The biasing lever is mounted in the handle and is mounted eccentrically and pivotally on the dial. The spring is mounted around the biasing lever and biases the biasing lever to rotate the dial in two rotational directions to retract or extend the blade. The assistant assembly assists the user to open or close the pocketknife.
