This series is truly unique although still based on the Big Three frames. By offsetting one loop and installing a gap between the loops, we have created a more ergonomic scissor with better control and dexterity, while reducing finger fatigue. Excellent with natural materials and can handle most synthetics. Fantastic if you tie with scissors in hand. FYI, your thumb goes in the standard loop.
