Double Edge shaving is cheaper, healthier, and more confidence inducing than cartridge shaving. Mach3 cartridges cost about $2.25/ea online, Double Edge razors cost $.10 each. Ingrown hairs arise when facial hairs are pushed into the deeper layers of your skin while shaving. This is a common occurrence when shaving with multi-blade razors, the first blade takes off a small piece of skin along with the hair, then the following blades push the remaining hair down into your skin producing ingrown hairs. Double Edge razor shaving uses one, exceptionally sharp, razor to shear the hair without damaging skin or pushing the root into deeper skin. Finally, you’re shaving with something sharp enough to cut steak like warm butter, not a cartridge full of half dull metal strips. This is serious business and you can cut yourself but it’s a skill you can master. Make shaving a ritual rather than a chore with the iKon Slant Double Edge Razor.
