Hello.

I decided to start Straight Razor shaving three years ago or so. Everything went well and tidy but year ago or so I decided that I shall for the first time, grow a full beard. So I mothballed my Straight Razor. I put it in to a airtight pack with some white rice to absorb moisture, and set it aside to wait for when I need it again. Today I decided to shave off my beard, so I went and dug out my old straight razor and this is how I found it:




I have no clue how is it even possible that the blade rusted, as I put it in to the pack dry. I even used hairdryer on it before I mothballed it.
Is there anything I can do to restore the blade? Or is it complete goner?
