Very Rusty Chisel Restoration

I found this chisel in steel piles from Japan. I can not find the production year and do not know how long it was abandoned. Rust eats the chisel blade badly, while the handle is rotten. I don’t know how original it looks. I try to re-shape the chisel blade and make a new handle by my imagination. I hope the result is acceptable. Furthermore, I am happy to receive feedback, suggestions to improve myself. Please share to me in the comment if you know more about this chisel. !!! I’m sorry for the mistake if I did in this video !!! Thank you very much for choosing to watch my video! Have a nice day Gear Show
