A Craft or trade is a pastime or a profession that requires particular skills and knowledge of skilled work. In a historical sense, particularly the Middle Ages and earlier, the tem is usually applied to people occupied in small-scale production of goods, or their maintenance, for example by tinkers. The traditional term craftsman is nowadays often replaced by artisan and by craftsperson (craftspeople).
There are three aspects of human creativity - Art, Crafts and Science. Roughly determined, art relies upon intuitive sensing, vision and expression, crafts upon sophisticated technique and science upon knowledge.
