Many customers ask why they should consider shaving with a safety razor and blades. There are a number of reasons to consider this classic and time proven method: An 8 pack of your typical four blade cartridge razors can set you back over $20. The cost of a double edged safety razor blade is substantially less. You can save additional money by using traditional shaving creams and soaps like Proraso, Speick, Musgo Real and Muhle Pinsel.
