My first antique blade, help with ID?

[AUhills79]

Here are the last three things left to translate.

1: The maker's mark.
2: The diamond shape symbol made with 9 dots.
3: The "xxx" or ">>>" symbol.

If these can be figured out I suspect that will help put an accurate date on the blade. I suspect there is only a limited slot in the timeline where all the symbols on this blade would of been used together.
