These are medically good scissors developed with an ergonomic design aimed at preventing wrist/carpal tunnel issues. We have reconsidered the location of the thumb-which is shorter than the other fingers-to make these scissors easier on the hands, locating the finger holes in the most natural place. Furthermore, to reduce strain on the gand, we have used a carbon resin bearing and titanium-plated wave washer. Whether you are troubled by wrist/carpal tunnel issues or whether you have never had any concerns about your hands, it is important for long-term use to choose a tool that will reduce the burden on your hand.
