The Great Wave Katana made by Paul Chen for Hanwei displays the Tomoe motif used frequently for family crests and shrine decoration. The koshirae (refers to the ornate mountings of a Japanese sword) are crafted in blackened iron and feature the Tomoe mon.
The bladeon the Great Wave Katana is hand-forged from T10 high-carbon steel featuring a long (o)kissaki and is differentially hardened to produce a distinctive hamon (visual effect created on the blade by the hardening process).
The saya (Housing or Scabbard for the blade) is deeply lacquered in black. The rayskin (protective handle covering) of the tsuka (Handle) has a premium woven Japanese black cotton wrap with a matching sageo (Braided Cord).
