#112 Classic Nakayama kiita koppa, this odd-shaped stone was harvested from a nook in the sediment layers. Perfect for what they were marketed as, for small craft and specialty blades like scissors and chisels and we here in the West use them for traditional kamisori. This kiita easily abraids a wide variety of steels including stainless and high carbon.
Super fast cutting and fine grit.
185mm long x 47 to 60mm wide x 25mm thick. 612 grams.
