I've been lurking far too long here, so time to start posting something hopefully worthwhile. So here are some photos of what was sold to me as a Mumei Muromachi era katana. Came to me in a Shirasaya mount with the original Koshirae included. (Apologies in advance for any terminology screw-ups or misspellings. I'm still learning.)
The blade's been polished a few times, I'm guessing it's Suriage by now, perhaps O-suriage? About 65.3 cm in length now. Three holes in the tang. The blade still seems quite nice to me, although the kissai seems a bit narrow, and perhaps was re-made during one of the polishings?
There's some ware in it, but nothing that (to me) seems extreme. No cracks in the blade. The hamon doesn't run off the edge anywhere that I can see.
No signature, or perhaps it was lost when the blade was shortened?
Obviosuly this isn't a premium piece, but for my budget, I'm really happy with it. Plus it's my first Muromachi (I hope), I've been wanting to get a sword from that era for some time now.
I'm not sure if the kanji written on the shirasaya contains any useful information? I'm unable to read it. Any assitance would be greatyly appreciated.
