The Kai 7250 is a 10-inch professional shear that is ideal for thicker, more difficult fabrics. The 7000 series scissors, including the 7250, are made of a high carbon, hardened stainless steel. 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 it allows for easier use. The 10-inch Kai 7250 is considered an ideal length for most sewing enthusiasts. Capable of cutting thicker fabrics with ease, the Kai 7250 meets almost all sewing project cutting needs.
