The Raptor Unokubi-Zukuri (Cormorants Neck) blade design is patterned after the shape of the Naginata, the powerful long-handled weapon popular between the 12th and 14th centuries. Notable for the strongly relieved shinogi-ji and diamond-shaped kissaki, the Unokubi-Zukuri provides excellent balance in a strong cutting blade.
The Raptor Series has been designed for the cutting practitioner who does not necessarily have access to mats but who wishes to practice and perfect his cutting technique. The blades are forged in 5160 high carbon steel and specially heat treated to produce very high resilience and greater tolerance of misdirected cuts than a conventional differentially tempered blade. The edge geometry is configured to facilitate the cutting of both soft and semi-hard materialswithout chipping, allowing the cutter a wide choice of targets.
