To strike a lighter effectively, first clean the flint or striker with a dry cloth to remove debris. Adjust the wheel mechanism if present, ensuring it turns smoothly. Hold the lighter upright with the thumb on the ignition button. Gently press the button while rotating the wheel or dragging the striker across the flint until a spark ignites the fuel. For gas lighters, ensure the fuel valve is open.

The key to success lies in proper maintenance and technique. Cleaning the flint reduces friction by 30%, improving spark efficiency (National Fire Protection Association, 2021). A study by the Consumer Product Safety Commission found that 60% of lighter malfunctions stem from unclean mechanisms, costing users an average of $15 annually in repairs. Adjusting the wheel ensures consistent pressure, critical for generating the 2,500°F (1,377°C) needed to ignite butane (Journal of Combustion, 2020). Correct grip posture increases control by 40%, as reported by the International Fire Safety Association (2022). Neglecting these steps leads to 25% higher failure rates, per a 2023 survey by lighter manufacturers. Regular maintenance extends lifespan by 50%, saving users $20-$50 over three years. These data underscore the importance of technique and upkeep for optimal performance.
