Allow me a few words about the maker of this tanto, Hiroshi Kojima, the 4th Naohiro...   I have known Kojima san for years and I regard him as one of the most open and helpful Japanese sword smiths. His only wish is to make swords and spread sword knowledge. He shares his sword knowledge willingly and teaches to focus on steel and its particles. He does not care about recognition, he plays down his own knowledge and his sword making skills in a way that reminds me of the best English tradition
