The new Derby USTA has worked great for me.... Ten different razors , ten different soaps and creams....Finished shave #10 this morning , and I will retire the blade out of boredom, this blade can go several more shaves for sure. USTA is a thick, not so flexible , unbranded, unmarked DE razor blade... No idea why they chose to have a blank blade.... Any of you boys that like to really stretch a blade out will enjoy this blade in your Lillicraps's hone, it should really give you many great shaves..$10 PER 100 , shipped, hard to beat. Photo is blade after 10 shaves, each shave on a 48 hour beard....
