SUPERFINE BLADES--Some info please?

My neighbor gave me this today. I would love some info as far as time period? I've never heard of this company.

 

Not only have I never hear of 'em, I've never seen 'em before.

 

Looking at the packaging, I would venture to say these are 30'/40's carbon steel blades. Don't think I would use them but it it's a pretty cool display

 

Awesome! I appreciate it. I would love to learn as much as I can about these! I'm in love with them!

 

Very cool for display

 

Are you going to use or display?
I have yet to find a vintage blade that agrees with me.
But that's me. I know several folks here that all they use are vintage blades.

 

I plan to keep & display. If I ever did sell, it would be to purchase a cool vintage Gillette razor.

 

I have no idea what sort of value or demand something like this would have.
