The Kai 7250 10" Professional Series Shear is perfect for thick and difficult fabrics. This size is ideal for most sewists, and meets the needs for almost all of your cutting needs. The 7000 Professional Series, including the 7205, 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 allow for easier use.
