Keichō irai shintō bengi
Keichō irai shintō bengi is a 1779 Japanese woodblock book on sword identification, published in Ōsaka by Kawachiya Tokubeē and written by Kamata Natae, who died in 1796. Its single page shows several long blades drawn upright in rows, each with an inscription and measurements printed beside it. A designer could take from it the strong vertical rhythm of parallel tapering shapes and the dense, ordered labeling typical of early Japanese technical print.
