The Sensei FIT hair cutting shear is a great new shear designed so that most people can comfortable use without the need for plastic finger insert rings. You will feel the comfort and how beautifully it FITs your fingers. The sculpted thumb will allow you to cut the elbow down in most positions. The Ball Bearing Tension system will allow the user to cut thicker sections of hair with less thumb pressure. The Bearing also stabilizes the blades and helps the blades operate more efficiently and smoothly. The polymer lined pivots extend the life of the shear and prevent wear by eliminating metal to metal wear. Made with Molybdenum Alloy Steel to give a smooth soft cut.
