Piezoelectric Mechanism: It features a built-in mechanical piezo-ignition system.Spring-Loaded Action: Pulling the trigger activates a tiny internal spring-loaded hammer.High-Voltage Spark: This hammer forcefully strikes an internal piezoelectric crystal, creating an electrical voltage that travels to the tip and produces a visible ignition spark.Zero Refills Needed: The system relies purely on physical friction and mechanical pressure, meaning it requires no batteries, no flints, and no gas fuel to function.
