The ad for this blade references Wilkinson technology which is misleading. These blades are actually made via licensing under Lord (which is made under the Wilkinson licensing empire). Wilkinson is a fine blade; Lord much less so.
I bought these Shark blades under a 99 cent special. They may be worth it at that price, but not their regular price of almost twice that much. While a smooth, forgiving blade, they only last about 2+ shaves. By the third shave they were tugging and dull as a butter knife.
I would recommend Wilkinson blades, but not Lords or these knockoffs.
The Russian Gillette's are the best overall value IMHO. I get 6 - 7 shaves out of the latter.
