Seiichi Fukagawa Saw Hand-bent Saw Log

This is a large Japanese saw (O-ganna) made by Seiichi Fukagawa.
Approximately 100cm when measured diagonally.
The blade is approximately 60cm long.

There are no chips on the blade, and no signs of use on the saw itself, so I believe it is unused. However, it has been stored for a long time, and there are some areas around the name where light rust has appeared.

Please feel free to comment if you have any questions.

Thank you for your consideration.
