Evolving from Butane torches used in industrial applications, the modern household torch shares a common lineage with those used by pastry chefs. While you may never use one of these to get the perfect sear on a Creme Brulee, the durable construction will ensure you never get burned. Piezo wire ignition powers the flame, creating a spark from electrical voltage, which ignites the Butane. This type of ignition is commonly favored in camping equipment, such as stoves, for its longevity and robustness.
