It can be argued that the Japanese took bladed warfare further than any other cold weapon civilization.  Samurai smiths spent months crafting their weapons using techniques that were performed with specific rituals to imbue the "Bushido" or "Samurai Spirit."  The Godfrey Knife and Forge Kaiken is a 5/1/2 inch fighting knife worthy of the Samurai warrior that doubles as a practical woodsman's tool.
