Contemporaries

Thank you guys for the input. I forgot to mention this, but does it also look like the kissaki might have been reshaped? The hamon tapers off drastically at the kissaki.

Hi everyone, I just started recently collecting and picked up a piece that caught my eye. Unfortunately I do not yet have much experience in the study and it is a mumei. But I was hoping for some advise on how I can study this, or if there is any sort of information that can be discerned such as the school, possible age, etc. It does look like it has been shortened before. Thank you in advance.
