Hi Bjorn,
The kissaki is poorly shaped. The fukura and ko-shinogi don't run parallel. Reshaped and that's why the hamon is lost or parts of the hamon are lost.
I have a wakizashi and have some difficulty with naming the type of the hamon. From the middle of the blade towards the tip there are some cloud shaped object. Some connected to the hamon but some are just floating around. Is it save to call this tobiyaki? Not the best pictures but I hope it's good enough.
Regards, Ed
Steve,
The definition of a wakizashi changed over time. Markus Sesko wrote a nice artikel about it.

You can also call your blade a Ko-Wakizashi (slightly bigger than a Tanto). So a ko-wakizashi in full navy Koshirae.
I believe the signature reads Bishu Osafune Sukesada but I'm not sure about it. The signature is hard to read. The date is also difficult but it looks from the Taiei (1521) era. Am I right? Feel free to comment. Al help will be highly appreciated.
Hi Tom,
Thanks for your reply. I'm still not sure. 石川 ishikawa fits better than 石州 sekishu. It's missing the little strokes.
We need the remaining part to solve this little mystery.
