Sets include aviation snips with different blade orientations to make straight, right curved (clockwise), or left curved (counterclockwise) cuts. The cut direction refers to how the waste material will come off the blades. Snip handles are color-coded yellow for straight, green for right, and red for left. The compound action of aviation snips increases leverage and reduces the force required to cut. They are commonly used to make short, straight, or curved cuts in aluminum, sheet metal, plastic, and cardboard.
