This is a very interesting sword made during WWII and signed “(Anchor stamp) Nobumichi Saku”.  The stamp with the anchor indicates a sword made for navel forces.  This sword is not a hand made or traditional made sword and is instead a sword made from stainless steel.  Some smiths/forges were experimenting with stainless because of the problems incurred by swords that were made from carbon steel that were carried by navel forces.  Carbon swords or traditional made sword tend to rust quickly in navel situations.  This is one of these swords made of stainless steel.  Overall its in very good condition and would fit very well in ay WWII collection.
