Motorola Razr V3 (2004)

The Motorola Razr V3 (2004) was the thinnest phone in the world at just 13.9mm, a stunning 45% slimmer than the average clamshell rival of its time. Its aircraft-grade aluminum body, laser-etched keypad, and iconic flip design made it the ultimate status symbol, selling over 130 million units by 2006 to become the best-selling clamshell phone in history. This design-forward approach set a standard for aesthetics that later smartphones, including the BlackBerry 6210, could not match.
