I found these blades to be excellent, and was lucky enough to purchase the last 60 Paul had in stock a while ago. He recently made them available again after 5-6 months of no one having em for sale. Yeah, more than a few people were upset that no vendors could get these anymore. Heh, I'd been rationing mine in the meantime.
I felt the Iridium blades to be similar to the Gillette SharpEdge (yellow).......as sharp and yet as forgiving. Longevity is good as well. Very much worth trying one of these if you can navigate to the site.
Hope that helps,
I can quit at any time that I decide to. Unfortunately, I have NO control over when (if ever) that decision might occur.
