The Birth of the Single Claw Model

The Single Claw model from Thorens made its debut in 1913, with patents granted on February 3, 1914, and November 16, 1920. Its cutout, asymmetrical design quickly captured the attention of lighter enthusiasts and established its popularity in the market.

Innovative Flint Mechanism

One of the standout features of the Single Claw lighter is its innovative flint mechanism. The design makes it remarkably easy to access and clear any obstructions caused by old, degraded, or hardened flint. Unlike other vintage petrol lighters, the shorter and open flint tube minimizes the risk of moisture intrusion, preventing potential damage. A lone long arm spring secures the flint in place against the file wheel, ensuring consistent performance.

Closed Tank Fuel System

The Single Claw pocket lighters feature a closed tank fuel system, reducing fuel evaporation significantly. Additionally, the fill screws are ingeniously designed with hidden storage compartments for extra flints, making it both practical and efficient for users.

The activation mechanism is equally impressive. The lighter operates via a spring-loaded button that prevents accidental ignition when fully screwed in. When unscrewed and depressed, the single-claw arm engages the file wheel and ignites in a smooth, clean motion.

Single Claw vs. Double Claw

While the Single Claw lighter is a remarkable piece of engineering, some enthusiasts believe the Double Claw model surpasses it in performance and design. However, the Single Claw remains a beloved classic, with its unique charm and historical significance.

Evolution and Enduring Popularity

Over the years, the Thorens Single Claw lighter has undergone continuous improvements, while staying true to its classic design. This commitment to quality and innovation has ensured its enduring popularity among vintage lighter collectors and enthusiasts.
