Quick adjustments. No screwdrivers needed, simply adjust sharpness using the Bevel Dial.
To get the best cut, start by adjusting the Bevel Blade to your liking. Just take the blade off of your razor and adjust the gap between the cutting blade and guide blade a few times until you find a length that gives you a shave you love without irritating your skin,
