Thread: Japanese Razor Talk!

Anchor chain was made of wrought iron and sometimes had cast iron reinforcements, neither of which make good cutting tools.

Wrought iron is used as the main body of many Japanese knives, but the cutting edge is usually some form of high carbon steel that is forge welded to the iron.

edit: (I just realized that in one of my posts above I said that the anchor chains were cast iron. That is a typo; the links are most commonly wrought iron, though some do have cast iron "cross braces".)
