Lord blades are underated very good great quility i use the ss from lord Everyday
Not sure if it's the same as the Lord Platinum, but I really like the Lord Platinum Class. I went 14 days on the last one I used.
I use a combo OC/SB razor, and normally use only the SB side. I flip the blade after 6-10 shaves, then do another 6-10 on the other edge. Lord Platinum are the only ones that do this without a declining shave quality. I could probably go more, I just feel I should change the blade out at that point. Lord SS are almost as good and forgiving as the Platinum.
