A flint wheel assembly is disclosed as including a flint wheel rotatable to rub against a flint for generating spark; and two outer wheels, each on a side of the flint wheel, and each operatively associated with the flint wheel via a respective inner wheel; wherein each outer wheel is movable substantially along its longitudinal axis between a first position in which it is out of contact with the inner wheel and a second position in which it is in contact with the inner wheel; and when the outer wheel is in the second position, the outer wheel is simultaneously rotatably movable with the flint wheel upon the application of a force on the outer wheel in a direction generally towards the inner wheel.
