Your straight razor will be honed using a natural progression that uses up to six different Nagura stones performed on this Shoubudani Mizu Asagi. This Nagura progression starts with a Tsushima or Botan and is followed through with Tenjou, Mejiro, Koma and Tomo. Each Nagura stone will be used to make a slurry on the Shoubudani Mizu Asagi. This slurry is then worked, thinned, diluted and repeated until the Honemeister feels it is time for the next Nagura stone slurry. Eventually finishing with a Tomo Nagura which is carefully selected by the Honemeister, depending on the qualities of the steel. This progression is time-consuming but leads to longer-lasting edges that are extremely sharp and totally smooth.
This beautiful stone is blue/grey in colour. It is extremely hard and dense and extremely fine in particle size.
