Ronin Elite Laminated Ko-Katana #19 - Bo-Hi Groove

This Ronin Elite katana has been traditionally forged and laminated in the soshu kitae tradition (seven panel steel). This school was developed by the legendary Japanese smith Masamune, and combines panels of hard, medium, and soft steels. The core of the blade is formed from softer, more malleable steel giving it exceptional flexibility. A layer of slightly harder steel is bonded to each side of the core to add support. The last layers are a very hard steel bonded to the top, bottom, and both sides of the core forming the ha (cutting edge) mune (back edge) and shinogi-ji (blade flats). This form of laminar construction provided for a sword that could be sharpened to a razor edge due to the hardened steed used for the ha, but was extremely resilient to battle damage due to its softer more flexible core.
