ABSTRACT:
A cigarette lighter for use with a volume of fuel includes a body. At least one projection extends from the body and defines at least one opening, which includes a first area bounded on at least one side by a curved leg and a second area bounded on at least one side by a flat leg. An ignition system includes a flint, a knurled wheel, and at least one elongated stub coaxial with the knurled wheel. A cross-section of the at least one stub has at least one flattened face. An engagement portion of the at least one stub extends into the at least one opening such that the knurled wheel is moveable between a first resting position wherein the engagement portion of the at least one stub is disposed in the second area of the at least one opening such that the at least one flattened face of the at least one stub communicates with the flat leg of the at least one opening to prevent the knurled wheel from rotating relative to the flint, and a second operational position wherein the engagement portion of the at least one stub is disposed within the first area of the at least one opening such that the knurled wheel is rotatable relative to the flint.
