This Shiro Suita is medium hardness with classic light blue/grey base color and Renge. Near perfect shape 50' size stone which is squarish overall. Classic Shobudani Shiro Suita with light blue/grey base color and aka Renge. appears to have some underlying Karasu patterns laying in wait as well. Perfect for knives and tools and great for pre finish of razors. Fast and crisp like most shobu suita and produces black swarf and self slurry immediately. Bright, hazy polish and toothy yet refined edges. Ultimate finishing stone for polishing and great to use after a softer suita or Uchigumori.
