Old Stock Shobudani Karasu Suita. Shobudani is one of the two original Honyama Mines along with Nakayama. Shobudani was revered for its diverse, high quality stones. Shobudani Suita are highly regarded for their fast cutting speed and polishing ability. They have become quite rare since mining has ceased decades ago. This Karasu Suita was mined from the Tenjou Suita layer and displays a vivid, multi-faceted surface with Tenjou Suita blue base which is absolutely covered with stunning Karasu patterns. Absolute monster of a Suita with Ooban, square shape and size. The sides of the stone show amazingly dense Karasu layers throughout the entire stone. The backside features beautiful, detailed hand chisel marks. Has an area with minor back chipping but otherwise, a nearly perfect piece! Finding a Karasu Suita of this size and purity is extremely rare today! Perfect for all applications including razors, knives, tools and swords. Performs very similarly to Uchigumori in all aspects
