The St Dupont flint wheel is a component commonly found in high-quality lighters, often crafted from durable materials such as stainless steel or brass. It serves as the ignition system for creating a spark, essential for lighting the fuel in the lighter. Characterised by its robust construction and precise engineering, the St Dupont flint wheel is designed for optimal performance and longevity. When rotated, it strikes against a flint, generating a spark that ignites the lighter's fuel to produce a flame. Renowned for its reliability, the St Dupont flint wheel exemplifies the brand's commitment to quality and innovation.
