Sword Flaws (Kizu)
Traditionally made Japanese swords are amazing works of art, but they are subject to flaws. Some flaws are fatal, while others non-fatal and may be polished out by an experienced togoshi. Here is a small list of kizu:
Ware are separations between the layers of steel. These are non-fatal and very common in older swords.
Shinae are wrinkles on the blade surface, sometimes indicating blade straightening. This is non-fatal and can usually be polished out.
A fukure is a blister, or a pocket in the steel. Blisters are ugly, but not fatal.
Hagire is a crack running through the hamon. It is a fatal flaw, and sometimes very hard to see.
