The Feather Adjustable Double Edge Razor is very similar to the Feather Popular Double Edge Razor. The difference is a unique feature that allows you to switch between a mild and aggressive shave. By switching the lever to '1' the blade has less exposure and gives a more mild shave. If you switch to '2' the blade becomes more exposed and gives a more aggressive shave. The adjustable blade exposure gives a personalized shave so you can determine what's best for your skin and hair type.
