The Vertigo Spark Torch lighters are truly a masterpiece in design and function. Fueled by liquid butane, just like regular lighters, this torch lighter forces the butane gas out through a narrow opening at high pressure prior to ignition, causing the flame to be much hotter. Ignition is caused by a small hammer striking a piece of quartz and creating a spark whenever you press the button on the lighter. Compared to a regular flame, the Vertigo Spark Torch lighter creates a much hotter and more forceful flame that is resistant to wind. This makes them ideal for outdoor use and for trades where a small portable flame might be needed for very minor heat-treating work. Also, torch lighters are far better at evenly lighting large cigars and some types of pipes. With useful features such as top-mounted pressure ignition switch and flip-top lighter cover, the Vertigo Spark is a must have for any cigar connoisseur.
