From everything I've read these are the same as the original SI's....these are not the same as the standard polsilvers...same factory, same blade, just different packaging. If these blades prove to be the same, I'm buying enough for a decade !!
I have used the beloved Super Iridium, and currently have a stash of 250 blades (thanks to one of our B&B vendors in Spain).
I would be very interested in trying the Polsilver version of these blades.
So If I am picked, all you would need to send is the Polsilver blades. I wouldn't want to cut into your stash of SI's since I have my own....
