Diplomat Injector Blades?

Hello

So I purchased a second Schick injector razor, I already have a Schick Injector Type J, I bought a Type L1, with my current Injector I usually use Schick proline b-20 blades that i insert in to my older Schick cartridges.

So with my recent purchase I got some NOS Diplomat blades that come in a plastic cartridge.






Says blades are made in the USA, the case in Germany and has Sheffield on the box too

So has anybody tried these blades? Any information available on them? What's your experience like with them? I tried searching the net to no avail.
 
Interesting find.
The patent number on the all-plastic case is the US version of this Swiss patent:
The inventor, Ernst Graf De Longuyon, had two more injector tricks up his sleeve:
The Supramat all-plastic injector razor: https://razors.click/patents/US3311975/ (rarely seen)
and an electric injector razor: https://razors.click/patents/DE1794636/ (probably never made)
He lived in Munich, Germany but most of his patents were assigned to the Swiss Climar AG company.

All these inventions are from the mid-60s, so whatever the blades are, they are probably not very good.
As they are rare, I'd keep them in the magazine. It's probably worth more than the razor
 
Very informative thank you.
