These knives are made from Silver 3 Steel (AKA Ginsan or Ginsanko) and we chose some really spectacular knives to offer from Konosuke to show off this excellent stainless steel. The blacksmith they chose is one of the top guys working in Sakai currently. These are two sided knives with 50/50 edges. They have a beautiful secondary bevel on each side that really sets the knife apart from others aesthetically. This one comes with a beautiful yew octagonal handle. Ginsan steel is excellent quality stainless steel so this knife will look as good as it performs. Konosuke is making some of the best knives we carry and this one is a beaut.
