KAI 7000 Professional Series Gift Set includes our most popular 7000 Series Shears. They are made of a heavy-duty, high-carbon stainless steel which allows these sewing shears to be sharpened at a steeper angle and allows them to maintain their cut-life and durability over time. If you are looking for high quality professional sewing shears that are great on cottons, denims, silks, fleece, and even Carbon fiber, Kevlar®, and Nomex® then Kai is the brand for you!
