EVANS Lift Arm Nickel Silver Kerosene Lighter

Strictly speaking, the lift arm concept was pioneered and popularized globally by British brand Alfred Dunhill in the 1920s. However, Evans did not simply copy this design; it made critical structural modifications. While Dunhill's flint wheel is positioned horizontally (requiring lateral actuation), Evans' designers innovatively reoriented both the flint wheel and flint tube to a vertical arrangement and redesigned the spring linkage. This change successfully circumvented Dunhill's early patents, representing an independently filed invention patent that re-engineered the internal mechanical layout within an established industry standard.
