For a long time now, along with the emancipation of left-handers (today a need for such a process is difficult to imagine; however, the left-handers were a discriminated group a few years back) the market of things designed specifically for their needs is growing. This is a real challenge for designers who usually have to rethink an object from scratch. It is not always enough just to reverse the design in order to get the desired result. The purpose of creating devices for left-handed people is to get in return a possibility of experiencing grasping in a similar way, no matter which hand a person uses.
