The 29 3/8"A Ko-Katana (also known as an O-Wakizashi) is one of the most versatile styles of Japanese blade. The ability to securely grip it with two hands allows the use of maximum force, with the shorter, more nimble blade clearing obstacles and able to be used in confined spaces where a full length Katana can inadvertently end up stuck in the ceiling. But this Tactical modern day variant by Ryujin takes it to the next level.. This version sports a tough, monotempered high quality 1060 carbon steel blade with smooth, clean lines and a partial bo-hi near the hilt, which is made from hard wearing ABS and triple pegged for the kind of durability the Samurai could only have ever dreamed of. Complimented with a modern wearable leather scabbard to make it the complete package.
