The Creative Grids® 45mm rotary cutter is designed with you in mind. The sleek red metal body adds weight to the cutter so less pressure is required when cutting fabric. The cushioned, comfort grip is designed to fit your hand, reducing slips and muscle fatigue. When the button is in the center, the guard fully protects the blade when not in use. Move the button a quarter circle to the left or right to expose the blade for right and left handed users
