SMHAEN fly tying scissors are the only scissors on the market that come with a unique color system that makes it easy to grab the right scissors when you are tying. Red are regular, all-purpose and hair scissors, blue are small, midge scissors with micro tips and green are larger heavier scissors. Made with Tungsten carbide blades for increased durability and edge retention, these Tungsten Carbide Green Large Straight Scissors have straight, sharp blades and are designed for tyers who work on bigger, heavier flies. All SMHAEN scissors come with large rings to improve grip, so you can precisely handle any soft or tough material.
