This is a really well designed shear that works great for high volume stylists, particularly if you are having problems with hand and wrist fatigue. The extra hole in the middle allows for the two middle fingers to be properly aligned. This is a big help in preventing problems with carpal tunnel syndrome. The swivel thumb allows natural movement, keeping your shoulder and elbow in a more relaxed and comfortable position. It is also slightly longer than your average shear at 6.5 inches. This means less cuts and less stress on your hand. This is a healthy and productive alternative to a tradtional shear.
