It is super clever as it is made like a Swiss army knife, and then features an additional tool, which is a case back opener knife. With that said, it features a number of other tools that may come in handy. Also, since it is a Swiss army knife, it is easy to carry and bring with you at any time. It has a design of a standard loupe but if you are going to wear it on your eye, it is pleasant to wear thanks to air circulation through the additional viewing port.
