Salon and barber Scissors / shears
There are several varieties of blades among hair scissors – beveled, semi-convex, convex – and all require a specific type of sharpening.
All sharpening, even the very best, requires the removal of steel by using an abrasive to cut off the dull or damaged edge.
What sets apart high quality sharpening is the removal of the absolute minimum of steel – usually less than half the width of a human hair.
The single most important factor that determines the lifespan of your shear
is the skill level of the sharpener. Proper sharpening will prolong the life of your shears.
