(Bloomery iron not to be confused with Wrought iron, it is a different method and is some thousand years older 
Bloomery iron is the material that is made in a bloomery furnace. The tatara is a bloomery furnace, too. European bloomery furnaces are mostly a lot smaller.
In furnace Charcoal and ore is transformed to an iron bloom.
Wrought iron is made in Puddel oven The initial material for this kind of production was raw iron, which, in fact, is cast iron. Made in a primitive blast furnace.
The raw iron was put in the wrought iron oven and heated by blowing super hot gas over it. The material went liquid and was then "stirred" to get the carbon out. It's a bit like stirring a thick dough and by doing so, the slag inclusions are drawn out and sometimes leave a layer like looking structure.)

All knives JNS cary is handmade and made one by one, so they can vary in size and thickness. Unevenness in finish can occur.
