For the home cook who has everything — except a Japanese knife stone! From the craftsmanship geniuses at Nasaki, this multi-layered stone is a more lo-fi (and more fun) way to sharpen your knives than the electric iteration. The instructions are refreshingly simple: "Use the #1000 (the red ochre one) for general use, and finish off with the #3000 (yellowish brown). Soak for five minutes before use and splash with water during use to keep wet."
