Every professional barber needs scissors to master their craft. Whether you need Professional Barber Scissors, thinning scissors, straight, left-handed or offset shears. We are sure to have your perfect cutting companion. One of the foremost important factors when choosing the proper shears is size. They need to suit your hand comfortably. Too small scissors for your hand limit your range of motion. Shears that are overlarge have a negative effect on your cutting motion. The industry standard for shears (by size) is 5.5 inches, and it’s the dimensions usually used when teaching future barbers and stylists. as long as your hands are larger than normal do you have to choose larger shears, such as 6.5-inch shears.
