We all know that scissors are the most important tools for professional hairdressers and barbers. Your reputation depends on how well they perform. They can also be dangerous to very very dangerous if care is not given.
Hairdressing scissors are made to be very sharp to cut perfect lines into the hair. So keeping them safe is just as important as keeping them from dulling. When the blades dull, they can cut jagged ends into the hair making it look like your client has split ends.
