Hair cutting is not a job. It's a craft.
Have you ever wondered what tools the barbers use other than those clips and the scissors??? Some men do not like to visit a barber shop for hair cut. They just trim their hair at home so that they can maintain it easily. While there are the others who visit the barber shop to get a different look with funky hair styles and also to pamper their hair, skin and feet with a good massage.
A barber's job which is as good as a craft requires skill and tools. It is an art with the hair irrespective of the length of the hair. There are some professional barber supplies in the USA and Canada that supply all tools other than the clips and scissors that a barber should possess to do a perfect, mind boggling job. There is a lot more for the barber to possess other than those hair cutting instruments.
Barber scissors: The most important tool that a barber requires is scissors. This is the tool used commonly by most of the old styled barbers and even now in some poor countries scissors are the only tools used for hair cut. Most of the barbers have two types of scissors. One has a pair of very sharp shears that is used commonly to ct the length of hair with either a comb or the length chosen by the barber with his fingers. The other is a pair of thin shears that is used to cut the hair to reduce the volume and make hair appear thinner.
