Hello friends i would like to know your opinion about dorco blades, i live in mexico in the Yucatan peninsula, the only blades i can get here at some Korean shop are this brand dorco. I used todaytwith my Merkur Barber Pole DE safety razor but i did only one pass with the grain. It was ok but i had not the confidence tu used against the grain, whats your advise on this.

By the way last month i went to florida and i bought some Merkur blades at the Aventura Mall but i havent used yet, what you think?
