Corrugation on Beauty Shears

Many German and German-style shears have small teeth on one of the cutting blades. This feature is called a corrugated blade, but why is it there?

German-style shears are generally designed and built with a blunter (less acute) edge angle. While this serves to give them better durability so you can go longer between sharpening than you would with shears made with a sharper (more acute) edge angle, this durability comes at a cost.

Since the blunter edge angle has a more difficult time cutting into the hair follicle, it is also more prone to pushing the hair. To prevent this pushing, shear manufacturers can sharpen small V-shaped teeth into one of the shear's cutting blades (the "corrugation"). The hair is then trapped between the teeth of the corrugation, which prevents the hair from pushing towards the shear's tips.

The professionals at Edgewise have both the equipment and the experience to both sharpen salon shears with a corrugated edge, and to re-establish the corrugated edge on salon shears, which have had it removed (usually by sharpeners, who are either unable to perform this technique, or who are unaware of the importance of the corrugation).
