Razor Blades

I trialled a lot of double edged razor blades with the Goodfella Safety Razor. The Derby Extra razor blades proved to be the best razor blade providing outstanding performance on quality and price. When you look at the cost of these blades you have to say why am I spending so much money on disposable multiple blade razor heads? I recommend that you change the razor blade every two weeks, though if you have sensitive skin or acne you should change the blade once a week as a dirty will irritate the skin and a sharp blade is less stress on sensitive skin.
