I had a gentleman contact a friend of mine asking for some help with a number of Nihonto he inherited from his father. His interest is in restoring them, and he wants to know if they are worth it. From what I can see, only one of the four may be. Unfortunately, the client brought them for modern American refinishing, but at least my friend knew enough to contact someone with more knowledge than himself. I only know enough to say they're legit, but little more than that. Any help with the mei would be greatly appreciated for my learning and experience. Thank you very much.
The first is suriage, with only one Kanji remaining, the second looks to be a Gunto blade (looks to have a Seki stamp), the third looks like a pretty tired U no Kubi zukuri wakizashi (worn down hi, double habaki, etc.), and the forth is now a broken and reshaped tanto.
