Precision haircuts depend on two things – your skill as a stylist and the performance of your shears.
The performance of your shear is largely determined by the characteristics of the cutting edges.
Substandard edges mean inconsistent cuts and may limit your choices in technique. Dry hair or wet, you simply can’t slide or slice with dull, damaged or poorly sharpened edges.
Even the best, most expensive scissors in the world are only as good as the guy who sharpens them.
There is no such thing as one-size-fits-all sharpening.
Different cutting techniques employed by the stylist require different edgework.
Different styles of shears require different methods of sharpening.
Variations in the quality of the steel from one scissor to the next require variations in the edgework to achieve the proper balance of sharpness and durability.
Very few sharpeners have the knowledge to match the scissor with the correct edge.
Scissors don’t die of old age or simply wear out. They are literally sharpened to death.
The single most important factor that determines the lifespan of your shear is the skill level of the sharpener.
All sharpening, even the very best, requires the removal of steel by using an abrasive to cut off the old dull or damaged edge. Done correctly, after precise shaping and polishing, a new edge is created in its place.
High quality sharpening removes only the absolute minimum of steel, usually less than half the width of a human hair.
Very few sharpeners have the experience, ability, technique or equipment to do this.
