A blacksmith is a metalsmith who creates objects from wrought iron or steel by forging the metal by using tools to hammer, bend, and cut (compare to whitesmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons.
While there are many people who work with metal such as farriers, wheelwrights, and armorers, the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to simple things like nails or lengths of chain.
The term "blacksmith" comes from the activity of "forging" iron or the "black" metal - so named due to the color of the metal after being heated (a key part of the blacksmithing process). The term "forging" means to shape metal by heating and hammering. "Smith" is from the Proto-German "smithaz" meaning "skilled worker."
