Straight edge blades are suitable for such hair cutting techniques as slice cutting and point cutting. Convex blades are suitable for thinning and smooth cutting techniques, because they are extremely sharp, therefore, they are chosen by professional hairdressers who demand the maximum of control, balance and comfort. It should be mentioned, that hair thinning shears have one or two blending teeth blades.

  • Bow is the arcuate outside part of the handle. It should be mentioned, that there are three types of handle – straight handle, semi-offset handle and full-offset handle. These three types mean three positions where the handle is placed in relation to the blades. It is very important to choose the right handle, basing on individual hair cutting techniques and specifics, because usage of incorrect handle can cause the Carpal Tunnel Syndrome. Repetitive wrist motions during hair cutting causes Median Nerve rubbing against the Carpal Tunnel. Repeating of this movement thousands of times day after day damages the nerve, causing tingling, numbness or pain in the thumb, index finger, middle finger or ring finger. To relieve the stress and minimize the risk of Repetitive Strain Injury or mentioned Carpal Tunnel Syndrome usage of hair cutting shears with crane handle or offset handle is recommended for most of stylists.
