In the 1930s, mainstream portable lighters suffered from poor wind resistance and easily extinguished outdoors, inside vehicles, or in windy conditions. Ronson developed the Whirlwind enclosed spiral airflow windproof chamber with a push-to-raise arm ignition mechanism. Its dual-layer metal cavity blocks wind while maintaining pocket-friendly portability and superior wind resistance. Standardized outer molds enabled mass production of enamel, engraved, and precious metal decorative versions, balancing everyday utility with collectible appeal.
