I have been using a "Double Edged" razor for about 10 years now, and pretty happy with the experience. I wouldn't go back to the cartridge based razors, no matter what.
Not sure about Pakistan, but abroad there are tons of forums dedicated to shaving talk. The knowledge and passion is just insane.
Recently, got interested in wanting to update my kit. That's where this purchase comes in. Had first shave using the new razor on Saturday, and it was great.
