I got this pack of blades in my WCS sample pack, and just got around to trying them. After finishing off the Feathers and red pack IPs, and not caring for a few others, I decided to throw one of these in the 50's SS, and it felt really good, almost the same as the red IP. There is not really a brand name that I can see on there, so I was wondering if anyone knows about these. WCS doesn't have them in their selection of blades either.
