The Raptor Shobu-Zukuri (Iris Leaf) Katana blade has an elegant shape and powerful cutting ability. Notable for the absence of a Yokote transition, this blade design became popular during the Nanbokucho era (1336 ~1392 AD) and its popularity continued into the Muromachi period. Designed under the auspices of cutting master James Williams, the Raptor Katana series has been crafted by Paul Chen for the cutting practitioner who does not necessarily have access to mats but who wishes to practice and perfect his cutting technique.
