Okay kiddo, do you know what a blacksmith does? They make things out of metal by heating it up and shaping it. Well, a bladesmith does something similar, but they specialize in making sharp things like swords and knives out of metal.
They start by choosing the right type of metal that will make a strong and sharp blade. Then, they heat the metal up in a super hot furnace called a forge. This makes the metal very hot and soft, so the bladesmith can hammer and shape it into the right shape and size.
Once the blade is the right shape, the bladesmith uses a special tool called a grinder to grind down the edges to make it sharp. They also add a handle made of wood or other materials, so people can hold onto the blade without hurting themselves.
Finally, the bladesmith polishes the blade so it looks shiny and new. And there you have it, a perfectly crafted blade made by a talented bladesmith!
