Abstract
A lighter includes a housing a housing that forms a fuel reservoir. The housing has a fuel outlet extending from the housing. A valve assembly controls the flow of fuel exiting from the fuel outlet. A flint is mounted on the exterior of the housing for lighting fuel released from the fuel reservoir. A flint actuator includes a spark disk to engage the flint and a driver disk fixedly connected to the spark disk. A third disk is disposed between the driver disk and the spark disk and is freely rotatable therebetween. The third disk has a diameter greater than the driver disk. A plate is disposed between the driver disk and the housing and has a radially outwardly protruding portion between the housing and the driver disk, which is aligned with the driver disk and extends radially outwardly a greater distance than the driver disk from a central axis of the housing.
