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. The blade itself is sharp, but with the patented  blade guard, it makes it safe for you and your client, meaning you won’t  cut yourself with this blade. The design also prevents hair from  clogging between the guard and blade.
