After repairing and using the 19th century tools, they were quite dangerous. 

When I stopped by a 93-year-old grandmother's house in the countryside,
A tool you've never seen before that was used in the Meiji era? Farm tools? Equipment?
I got (it seems to be a thing called push-cut).
This is like the Western guillotine turned upside down.
I thought about recycling it, but when I tried using it, it was incredibly sharp.
It is dangerous to leave it, so I decided to seal it.
