Summerizer

That's for reply guys! I'm gonna try and take much better pics this weekend. I can say that the hamon is much more visible on one side than the other, and is consistent along the entire edge to the tip.

And the rest... It looks to me like the habaki and shirasaya may not be original to the blade, unless I'm unaware of poor fitting after decades or centuries of being in storage. The geometry just seems a little off. It's in old polish and looks really nice in hand but tons of little scratches show up in the pics.

More pics...

Hi, brand new to the forum. Have lurked previously. I know there are tons of these post. I recently got my first nihonto, it's mumei, I'm just looking for a little validation and info on how to date this properly, where to start and even if this could be tracked to region or maker. Thanks for your time and all advice or info is appreciated.
