Shiro Kamo Yoru Blue #2. "Yoru" means "Night" in Japanese and these blades have the nice kurouchi blacksmith finish that bears their name. The blades are reactive so you need to dry them after using to keep them from rusting. The knives have nice walnut octagonal handles that are durable and attractive. These are great values from one of the master blacksmiths from Echizen.
