This is a set of two kiridashi knives from Ogura Chokoku Hamono Seisakusho, a blacksmith in Koshigaya City, Saitama Prefecture. The maker's mark is "Chotosei." The steel is Aogami (Blue Paper) No. 2. There is a left and a right. Please refer to the images for the width and size. They cost about 7,000 yen each, so I think this is a great deal. I am selling them because I haven't had a chance to use them since I bought them. #kiridashi #knife #kiridashiknife #carvingknife
