Why did my newly sharpened scissors dull out so quickly?

A novice sharpener will simply POLISH the outer edge and smooth out the inside of blades instead of sharpening the scissors correctly for fear of disfiguring the edge. The scissors will be dull again within 2-3 haircuts! A lot of times a novice sharpener is afraid of showing their work by leaving a distinct line of demarcation (a wavy blade or bevel). Leaving a weak line is caused by poor control and lack of skill and experience when sharpening the higher end softer steel shears. Consider yourself fortunate because once any metal is removed it cannot be replaced!
