The Raptor series of katana by Paul Chen/ Hanwei has been fashioned after the personal Nami Ryu swords of cutting master James Williams. The blades have been forged from 5160 high-carbon steel then mar quenched to an edge hardness of 57HRc allowing for cutting of both soft and semi-hard materials without chipping. All weapons in the Raptor line feature a full length, double pegged tang, blackened iron tsuba, a wood core handle with genuine rayskin wrapping, and a special non-stretch wrap for a firm grip and wear resistance and Raptor feather hilt ornaments. The Fuchi/Kashira fittings are blackened steel with brass ferrules (Habali). The wood saya has a non-fingerprinting textured lacquer finish.
