Hello, seniors! I am a novice-level katana enthusiast. Due to my lack of knowledge, I have many questions to ask you. I have recently collected some antique katana, but it seems that the problem described in my title is common. I would like to ask the following questions:
1 If the appraisal certificate of the Japan Art Sword Association does not mention the katana's accessories, can it be understood that only the katana itself was appraised, and the matching accessories are likely to be added later, rather than the same period as the katana itself?
2 If there is only one hole on the handle of the katana's accessories, and the katana itself has two holes, can it be determined that the katana's accessories were added later?
3 Is this phenomenon common in current katana transactions? I have seen very high-level katana with two appraisal certificates, one for the katana itself and one for its accessories. For a transaction, is this phenomenon normal or is the seller responsible?
4 How should I deal with this problem if I want to solve it?
Below is the latest knife I received. It is obvious that there is a large gap at the tsuba position, which is the reason for the looseness after assembly.
