Kurosaki san is young for a blacksmith, but he has the skills. The 'X' Suminagashi pattern is made by a special hammer he designed. This series is named Shimo (frost) because the blade looks like frost on a window. These blades are not made with stainless steel and require a bit more care. Keep the blade dry to avoid tarnish and if you ever see a bit of rust on the blade remove it immediately with a coarse dish scrubber and soapy water.
