Dr. Slick scissors are the choice of fly tyers worldwide. Whether you're new to fly tying or a hardened production tyer, Dr. Slick scissors will maximize your fly tying enjoyment, production and quality. Each scissor is inspected, adjusted and tested before leaving the Dr. Slick shop, assuring you a tool that won't fail on the bench. Dr. Slick Tungsten Carbide Scissors, this series has T.C. blades welded onto the scissor blade frame. T.C. is 7x harder than stainless steel and holds an edge longer. These can handle all types of tying materials, but were created to tackle modern synthetic materials. Available in three sizes: 3.5" Tungsten Carbide Arrow Scissors (Straight)4" Tungsten Carbide All Purpose Scissors (Straight)4.5" Tungsten Carbide Hair Scissors (Straight) For maximum performance and longer scissor life, two main rules apply when choosing scissors for tying. First, match the scissor to the types of materials you tie with most often. Most scissors in the Dr. Slick line can handle both natural and synthetic materials with ease, but if you tie predominantly with synthetic materials, consider the new generation of scissors like Tungsten Carbide, Razor and Prism that are designed to handle these materials. Second, match the scissor to the size and type of flies you tie. If you tie small flies without much mass or material, use small finer blade scissors like Arrow, MicoTip and Iris. Conversely, if you tie larger flies, with more mass and material, consider larger scissors with heavier blades like All Purpose, Hair or Razor. Great scissors make great flies!
