Abstract
The lighter of the present invention provides a resiliently deformable guard that covers a portion of the striking wheel assembly. To operate the lighter, a user exerts sufficient pressure to depress the guard before rotating the striking wheel assembly. Additionally, the lighter of the present invention provides blocking members to engage the deformable guard when the user depresses the valve actuator before exerting pressure to depress the guard.
