FEATHER� has set the standard in manufacturing the sharpest and safest razor cutting blades in the industry. The cutting edge of the FEATHER� blade is designed to give you the cutting control you need to be creative. The blade fits snug into the handle and does not chatter or move when cutting. Although surgically sharp, these blades are very safe for you and your client with its patented blade guard, which prevents the guard from moving and exposing the blade. This also prevents hair from clogging between the guard and blade.
