SENSEI FIT shears are designed to fit the average stylist without the need for any plastic finger rings. Beautifully sculpted to fit every contour of your hand. The Japanese Molybdenum alloy, SENSEI Cryo Tempered blades, are very durable. The pivots are lined with polymer inlays to eliminate metal to metal contact and extend the like new life of the shear. The ball bearing tension system provides blade stability and longer edge life.
