A food-processing device for chopping, mixing, or liquefying foods. The device comprises a container, a removable base, and a blender base. The container comprises a locking member located at the periphery of the container. The container has an opening. The removable base comprises a blade member and is removably affixable to the opening of the container. The blender base comprises a motor and a recessed well. The recessed well comprises a pressure-activated switch and a locking groove located adjacent to the switch. The removable base is adapted to removably fit within the recessed well such that when the locking member contacts and depresses the switch, the downward movement of the switch activates the motor, wherein the container can be depressed and rotated to allow the locking member to engage the locking groove, thereby permitting continuous operation of the motor without requiring a user to exert constant pressure on the container.
