This is a set of chisels, likely the "Yakko-nomi" type, made by the second-generation Shoji Nagaoke of Nagaoke Kikuhiro Maru Seisakusho in Sanjo City, Niigata Prefecture. I believe these were made by the second-generation Shoji Nagaoke. I received these from someone else, so I don't have all the details, but here's what I've found: The maker's mark is "Kikuhiro Maru," and it's a set of 10 chisels. The current generation is the third, but as my purchase was over 30 years ago, these are likely a rare work of the previous generation. Due to long-term storage, some of the "Kikuhiro Maru" stickers on the handles are faded. The outer paper box has scratches. I have checked the chisels, and there is some discoloration and rust on the handles and blades. The box has also deteriorated and is missing its lid. Please check the condition in the photos. I am not an expert, so please understand that there may be omissions in the description and the storage conditions.
