The Kai 7300 is the 12-inch professional scissor that is designed for use on thicker, more difficult fabrics or on multiple layers. It is also considered an ideal length for upholsterers and upholstery projects.

The addition of carbon allows for a steeper cutting angle, giving the scissor a sharper, finer edge. The carbon allows the finer edge to last longer. This gives the 7000 series a better ability to cut thicker fabrics and allow for easier use.
