A really really long and narrow Nakayama kiita 199mm long by 45mm wide is perfect for long X stroke razor honing. Double sided, each side is the same hardness and fineness. The dark kiita side is more rectangular, the lighter asagi side has a convex profile to the one edge. Being about 24mm thick is does sit well in the hand but because it leans towards a trapezoid shape as seen from the end, it does not sit well in a stone holder. A true razor hone, hard and fine and it works best for me with a diamond plate generated slurry. One corner as a sparkly portion of black kawa that suggestes Nakayama, the round mokume tree ring pattern helps confirm the provenance.
