A calm, lustrous steel is the first thing the connoisseur's eye is meant to settle on with the Rai school: a finely forged ko-itame (小板目) worked until it is dense and refined, over which the ji-nie lies thickly in minute particles, fine chikei (地景) enter, and a nie-utsuri rises in the ji. This bright, refined jihada, the surface the trade reads as Rai-hada when its softer, looser patches intrude, is the constant beneath every manner the house produced. Learn more →
