Best Selling Blades

Does anyone know what the best selling DE blade is?
In US?
The world?
I have no idea but I’d guess GSB, maybe even Astra SP?
Any wholesalers know??

Hmm , I wonder how to find out? Maybe look on retailer and filter best selling.
 This wouldn't be much more than a snapshot of their buyers.

I think it might depend a lot upon where you live. In the States, both Amazon and Maggard Razors show Astra SP blades as the most popular DE blades. Some of their popularity, however, comes from their low price. They are not necessarily the best blades; it depends upon your needs.

Considering the huge population of China and India, I suspect the best selling DE razors blades worldwide may be some brand produced in one of those countries.

Worldwide, however, multi-blade cartridges probably win the popularity contest.
