skate board

A skate board is a narrow wheeled platform used for the activity of skate boarding. Though the exact date of invention of skate boards is unknown, it was in the 1940s and 1950s that children participated in soap box derbys where they would race soap-boxes attached to wooden planks on rollerskate wheels. During events like this, some of the soap-boxes became detached from the planks, leaving the rider with what was a skate board. The first skate boards were made by taking a roller skate apart and attaching it to a two-by-four. These early skate boards were often used by surfers as a substitute when the waves were low. The skate board has evolved a lot since the first mass produced models in the 1960s. Boards in the past were often in the shape of a surfboard, with no concavity and constructed of solid wood or plastic. The wheels were usually made of a 'clay' composite or steel and the trucks (axles) were less sturdy and initially of a 'single action' design compared to today's 'double action'. China is the leading producers of skate board.
