"When Toshio Tokunaga needs irons for his selection of kanna (handplanes and spokeshaves), he turns to Master Smith Yasuhiko Ohara to have them made from scratch, the traditional Japanese way. Which as it turns out, is quite the pain in the ass—because Japan doesn't have any iron mines. With no ready source of ore, that means they get their iron particles by sifting through the sand at the bottom of a river."
