Help With Wakizashi

[javier]

Hello colleagues as mentioned in my previous posts I am beginner in nihonto and new owner of a humble tired and rusted wakizashi with delaminations but I am really interested in learning more about it.

The blade is o-suriage with three mekugi ana, ihori-mune, chu-kissaki

The jihada looks itame

The hamon looks notare with nioi

The boshi is very difficult to discern

Any additional imput and guidance will be highly apreciated, I understand that from the pictures is very hard to tell but if possible I will also apreciatte any help in determinating if the blade is koto, shinto, etc period and also if possible school.

best regards
Javier
