What seperates Hair cutting shears from regular shears?  Most people don’t know.  A regular shear usually comes with a bevel edge and has the tendency to have a very blunt weak edge.  Most shears don’t need an extra sharp edge because they are usually need to cut through paper, plastic, fabric, or other things.  A hair cutting shear needs to feel softer and smoother when sliding through delicate hair.  That is why the edge on good hair cutting shears tends to be 35 degrees or higher.  Many good hair shears also come with a convex edge which adds to the smoothness of the cut.  Anything less would make the stylists job unbareable.
