GEM single blade help

[Nova316]

I won a bunch of these off Ebay and have no idea where they are from or if they are good or not. They seem pretty good as they were still in the container. This was part of a lot and these are just extras.
Any one have any idea about how old they are, or if they are worth shaving with? I got some stainless ones PIF'ed to me from Dieselfuel79 and am very new to SE. I rather not chew up my face if they aren't good blades.

Thanks

They seem to be coated like the PTFE blades a lot of us use today.

Just give them a try and see if they work for you, or you could PIF a few and use other B&Bers as your guinea pigs!
