Dr. Slick Twisted Loop Arrow Scissor- Twisted Loop Arrow Scissors are an ergonomic, patent pending product from Dr. Slick. By offsetting one loop and installing a gap between the loops, Dr. Slick has created an ergonomic scissor with better control and dexterity, while reducing finger fatigue. They are available in 4" All Purpose. The 3.5" and 4.5" version are available upon request. The serrated blade cuts with perfection.
