 The company produces replicas or reconstructions of Japanese swords, Chinese swords and European swords, besides various types shorter-bladed daggers, sidearms or combat knives, other historically-inspired weapons such as axes and polearms, and reconstructions of historical helmets.Their production of Japanese swords (katanas) ranges from inexpensive swords made from differentially hardened spring steel ("Practical" series) to more elaborate production methods approximating traditional hand-forged folded steel blades starting from powder steel.The "L6 Bainaite" series is produced based on L6 steel, by means of a heat treatment process resulting in blades exhibiting Bainite/Martensite microstructures, a process pioneered by Howard Clark of "Omimi" and adopted by Hanwei from c. 2012.
