Description: Double-edge razors, often known and referred to as safety razors, utilize a single razor blade with two sharp sides – one on each end of the razor handle. The skin is protected from all but the edge of the razor with a guard, hence “safety razor.” Affordability: Replacement blades are more affordable than current multi-blade razors and the thinking is that their two sides extend each unit’s lifespan. Better Access: In many cases, the blade’s slimmer design enables improved access and removal of hair in tough-to-reach areas like under the nose and neck crevices. Closeness: Many feel these blades provide a closer and smoother shave than multi-blade counterparts. Benefits of "Butterfly Design" Speed to open. Safety while loading blade.
