The Kai 7100, 4" scissor is ideal for tasks that require a small but powerful cutting tool. The blade is made of a high-carbon stainless steel that ensures a sharp cut, all-the-way to the tip. It also features large handles made of "Elastomer" soft plastic, which are designed for better leverage and ease of handling while cutting. Great for detailed tasks such as thread snipping, embroidery projects, Hardanger embroidery, beadwork, rug-hooking and appliqué projects. 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 also allows the finer edge to be more durable, which in-turn, extends the cutting life of these professional scissors.
